Chalo Chatu:Copyrights
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
Permission is granted to copy, distribute and/or modify Wikipedia'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.
Contributors' rights
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.
