Rhea Copyrights Statement

Modified from Wikipedia's copyrights [1].

Important note: All contributions to Rhea are considered to be released under the GNU Free Documentation License 1.2. If you do not want your writing to be edited mercilessly and redistributed at will, then do not submit it here. You are also promising us that you wrote this yourself, or copied it from a public domain or similar free resource. DO NOT SUBMIT COPYRIGHTED WORK WITHOUT PERMISSION!

Rhea does not own copyright on its pages texts and illustrations. However, the Rhea-bird logos, the kiwi bird logo, as well as the student-driven learning concept are trademarked. They are not freely usable without permission.

Rhea's 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 Rhea article used is included (a link back to the article is generally thought to satisfy the attribution requirement). Copied Rhea 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.

To this end, permission is granted to copy, distribute and/or modify Rhea's content 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 and obligations

If you contribute text directly to Rhea, 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. 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.

Linking to copyrighted works

Since most recently-created works are copyrighted, many Rhea pages link to copyrighted material. It is not necessary to obtain the permission of a copyright holder before linking to copyrighted material. However, if you know that an external Web site is carrying a work in violation of the creator's copyright, do not link to that copy of the work. An example would be linking to a site hosting the lyrics of many popular songs without permission from their copyright holders. Knowingly and intentionally directing others to a site that violates copyright has been considered a form of contributory infringement in the United States [2]). Linking to a page that illegally distributes someone else's work sheds a bad light on Rhea and its editors. The copyright status of Internet archive's in the United States is unclear, however. It is currently acceptable to link to internet archives such as the Wayback Machine, which host unmodified archived copies of webpages taken at various points in time. In articles about a website, it is acceptable to include a link to that website even if there are possible copyright violations somewhere on the site.

Context is also important; it may be acceptable to link to a reputable website's review of a particular film, even if it presents a still from the film (such uses are generally either explicitly permitted by distributors or allowed under fair use). However, linking directly to the still of the film removes the context and the site's justification for permitted use or fair use.
