== Contributors' rights and obligations ==
If you contribute material to WikipediaAkvopedia, you thereby license it to the public
under the GFDL (with no invariant sections, front-cover texts, or back-cover
texts).
Never use materials that infringe the copyrights of others. This could create legal liabilities and seriously hurt the project. If in doubt, write it yourself.
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 WikipediaAkvopedia. However, it would still be unethical (but not illegal) to do so without citing the original as a reference. See [http://en.wikipedia.org/wiki/Plagiarism plagiarism] and [http://en.wikipedia.org/wiki/Fair_use fair use] for discussions of how much reformulation is necessary in a general context.

=== Linking to copyrighted works ===
# The length and nature of these invariant sections and cover texts does not exceed what can be placed in an edit summary;
# You are satisfied that these invariant sections and cover texts are not listed elsewhere than in the "page history" of the page where these external materials are placed;
# You are satisfied that further copies of Akvopedia content are distributed under the standard GFDL application of "with no Invariant Sections, with no Front-Cover Texts, and with no Back-Cover Texts" (in other words, for the copies derived from wikipediaAkvopedia, you agree that these parts of the text contributed by you will no longer be considered as "invariant sections" or "cover texts" in the GFDL sense);
# The original invariant sections and/or cover texts are contained in the edit summary of the edit with which you introduce the thus GFDLed materials in Akvopedia (so, that if "permanent deletion" would be applied to that edit, both the thus GFDLed material and its invariant sections and cover texts are jointly deleted).
Seen the stringent conditions above, it is very desirable to replace GFDL texts with invariant sections (or with cover texts) by original content without invariant sections (or cover texts) whenever possible.
''In Akvopedia'', such "fair use" material should be identified as from an external source (on the image description page, or history page, as appropriate). This also leads to possible restrictions on the use, outside of Akvopedia, of such "fair use" content retrieved from Akvopedia: this "fair use" content does not fall under the GFDL license as such, but under the "fair use" (or similar/different) regulations in the country where the media are retrieved.
Akvopedia does use some text under licenses that are compatible with the GFDL but may require additional terms that we do not require for original Wikipedia Akvopedia text (such as including Invariant Sections, Front-Cover Texts, or Back-Cover Texts). When wanting to contribute such texts that include Invariant Sections or Cover Texts to Akvopedia/.
