I'm trying to host a wiki website which is similar to Wikipedia: all contents licensed under Creative Commons Attribution-ShareAlike License. Besides putting a footnote at each page to explicitly declare the license, what and where should I put the legal language to inform that every contributor must contribute under this same license (and if they do contribute, they automatically agree with it)?

    Does the software require those who edit be logged in using an account? Can you control the account creation process? Commented Aug 29, 2015 at 23:06

    @JasonAller Yes, they must log in. But the registration is public.

  • @JasonAller I think you mean to acknowledge users about it when they create the accounts. But I don't understand why the standard MediaWiki does not provide such a feature to add an acknowledgement when creating the accounts. Also, Wikipedia itself does not use this way. These really make me confused.

  • If you edit something in Wikipedia, it says near the textarea: "Work submitted to Wikipedia can be edited, used, and redistributed—by anyone—subject to certain terms and conditions."

At the bottom of every edit screen on Wikipedia, above the "save page" button, it says:

By clicking the "Save page" button, you agree to the Terms of Use and you irrevocably agree to release your contribution under the CC BY-SA 3.0 License and the GFDL with the understanding that a hyperlink or URL is sufficient for CC BY-SA 3.0 attribution.

If you are asking for technical details on how to show that on a MediaWiki installation, that question could probably be better asked at another site. Regardless, on a standard MediaWiki installation, that text may be found and modified at the [[MediaWiki:Copyrightwarning2]] (sometimes [[MediaWiki:Copyrightwarning]]) page of the wiki.

  • Also, you would do good by setting $wgRightsPage $wgRightsUrl $wgRightsText
