The text of Chalo Chatu is copyrighted by Chalo Chatu editors and contributors and is formally licensed to the public under one or several liberal licenses. Most of Chalo Chatu's text and many of its images are co-licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC BY-SA) and the GNU Free Documentation License (GFDL) (unversioned, with no invariant sections, front-cover texts, or back-cover texts). Some text has been imported only under CC BY-SA and CC BY-SA-compatible license and cannot be reused under GFDL; such text will be identified on the page footer, in the page history, or on the discussion page of the article that utilizes the text. Every image has a description page that indicates the license under which it is released or, if it is non-free, the rationale under which it is used.
The licenses Chalo Chatu uses grant free access to our content in the same sense that free software is licensed freely. Chalo Chatu content can be copied, modified, and redistributed if and only if the copied version is made available on the same terms to others and acknowledgment of the authors of the Chalo Chatu article used is included (a link back to the article is generally thought to satisfy the attribution requirement; see below for more details). Copied Chalo Chatu content will therefore remain free under appropriate license and can continue to be used by anyone subject to certain restrictions, most of which aim to ensure that freedom.
Permission is granted to copy, distribute and/or modify Chalo Chatu's text under the terms of the Creative Commons Attribution-ShareAlike 3.0 Unported License and, unless otherwise noted , the GNU Free Documentation License. unversioned, with no invariant sections, front-cover texts, or back-cover texts.
If you contribute text directly to Chalo Chatu, you thereby license it to the public for reuse under CC BY-SA and GFDL (unversioned, with no invariant sections, front-cover texts, or back-cover texts). Non-text media may be contributed under a variety of different licenses that support the general goal of allowing unrestricted re-use and re-distribution.
If you want to import text that you have found elsewhere or that you have co-authored with others, you can only do so if it is available under terms that are compatible with the CC BY-SA license. You do not need to ensure or guarantee that the imported text is available under the GNU Free Documentation License, unless you are its sole author. Furthermore, please note that you cannot import information which is available only under the GFDL. In other words, you may only import text that is (a) single-licensed under terms compatible with the CC BY-SA license or (b) dual-licensed with the GFDL and another license with terms compatible with the CC BY-SA license. If you are the sole author of the material, you must license it under both CC BY-SA and GFDL. If the material, text or media, has been previously published and you wish to donate it to Chalo Chatu under appropriate license, you will need to verify copyright permission through one of our established procedures. If you are not a copyright holder, you will still need to verify copyright permission
You retain copyright to materials you contribute to Chalo Chatu, text and media. Copyright is never transferred to Chalo Chatu. You can later republish and relicense them in any way you like. However, you can never retract or alter the license for copies of materials that you place here; these copies will remain so licensed until they enter the public domain when your copyright expires (currently some decades after an author's death).
Using copyrighted work from others
All creative works are copyrighted, by international agreement, unless either they fall into the public domain or their copyright is explicitly disclaimed. Generally, Chalo Chatu must have permission to use copyrighted works. There are some circumstances under which copyrighted works may be legally utilized without permission. However, it is our goal to be able to freely redistribute as much of Chalo Chaty's material as possible, so original images and sound files licensed under CC BY-SA and GFDL (unversioned, with no invariant sections, front-cover texts, or back-cover texts) or in the public domain are greatly preferred to copyrighted media files used under fair use or otherwise.
If you want to import media (including text) that you have found elsewhere, and it does not meet the non-free content policy and guideline , you can only do so if it is public domain or available under terms that are compatible with the CC BY-SA license. If you import media under a compatible license which requires attribution, you must, in a reasonable fashion, credit the author(s). You must also in most cases verify that the material is compatibly licensed or public domain. If the original source of publication contains a copyright disclaimer or other indication that the material is free for use, a link to it on the media description page or the article's talk page may satisfy this requirement. If you obtain special permission to use a copyrighted work from the copyright holder under compatible terms, you must make a note of that fact (along with the relevant names and dates) and verify this through one of several processes.
Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt Chalo Chatu. If in doubt, write the content yourself, thereby creating a new copyrighted work which can be included in Chalo Chatu without trouble.
Note that copyright law governs the creative expression of ideas, not the ideas or information themselves. Therefore, it is legal to read an encyclopedia article or other work, reformulate the concepts in your own words, and submit it to Chalo Chatu, so long as you do not follow the source too closely.
Linking to copyrighted works
Contributors who repeatedly post copyrighted material despite appropriate warnings may be blocked from editing by any administrator to prevent further problems.
If you suspect a copyright violation, you should at least bring up the issue on that page's discussion page . Others can then examine the situation and take action if needed. Some cases will be false alarms. For example, text that can be found elsewhere on the Web that was in fact copied from Chalo Chatu in the first place is not a copyright violation on Chalo Chatu's part.
If a page contains material which infringes copyright, that material – and the whole page, if there is no other material present – should be removed.
Guidelines for images and other media files
Images, photographs, video and sound files, like written works, are subject to copyright. Someone holds the copyright unless they have explicitly been placed in the public domain. Images, video and sound files on the internet need to be licensed directly from the copyright holder or someone able to license on their behalf. In some cases, fair use guidelines may allow them to be used irrespective of any copyright claims.
Governing copyright law
The Chalo Chatu Foundation is based in the Zambia and accordingly governed by Zambian copyright law.
Reusers' rights and obligations
Re-use of text Attribution
To re-distribute text on Chalo Chatu in any form, provide credit to the authors either by including a) a hyperlink (where possible) or URL to the page or pages you are re-using, b) a hyperlink (where possible) or URL to an alternative, stable online copy which is freely accessible, which conforms with the license, and which provides credit to the authors in a manner equivalent to the credit given on this website, or c) a list of all authors. (Any list of authors may be filtered to exclude very small or irrelevant contributions.) This applies to text developed by the Chalo Chatu community. Text from external sources may attach additional attribution requirements to the work, which should be indicated on an article's face or on its talk page. For example, a page may have a banner or other notation indicating that some or all of its content was originally published somewhere else. Where such notations are visible in the page itself, they should generally be preserved by re-users.
- If you make modifications or additions to the page you re-use, you must license them under the Creative Commons Attribution-Share-Alike License 3.0 or later.
- If you make modifications or additions, you must indicate in a reasonable fashion that the original work has been modified. If you are re-using the page in a wiki, for example, indicating this in the page history is sufficient.
- Each copy or modified version that you distribute must include a licensing notice stating that the work is released under CC BY-SA and either a) a hyperlink or URL to the text of the license or b) a copy of the license. For this purpose, a suitable URL is: http://creativecommons.org/licenses/by-sa/3.0/

Additional availability of text under the GNU Free Documentation License
For compatibility reasons, any page which does not incorporate text that is exclusively available under CC BY-SA or a CC BY-SA-compatible license is also available under the terms of the GNU Free Documentation License . In order to determine whether a page is available under the GFDL, review the page footer, page history, and discussion page for attribution of single- licensed content that is not GFDL-compatible.
Reusing text within Chalo Chatu
When you merge or split an article, or otherwise move text from one page to another within Chalo Chatu , the page history functionality cannot by itself determine where the content originally came from. This may violate the attribution clause of the project's licenses. If you are copying text within Chalo Chatu, you must at least put a link to the source page in an edit summary at the destination page. It is encouraged to do the same thing at the source page, and to add notices at the talk pages of both.
If you reuse text which you created yourself , the above may still be a good idea to avoid confusion, but it isn't mandatory.
If you are the owner of Chalo Chatu - hosted content being used without your permission
If you are the owner of content that is being used on Chalo Chatu without your permission, then you may request the page be immediately removed from Chalo Chatu;
You can contact our designated agent (chabota@Chalochatu.org) to have it permanently removed (but it may take up to a week for the page to be deleted that way). Either way, we will, of course, need some evidence to support your claim of ownership.
