As we now have a new website and new data, is this not the right time to clarify the intellectual property rights of material added by users? I strongly recommend that when subscribing / joining a user (or new member) is required to confirm a couple of issues:
That all material submitted becomes available in the public domain under a Creative Commons licence (there are a number of different licence categories - see here for an example); I recommend the license to be that of "Attribution-NonCommercial-NoDerivs 3.0 Unported" which is represented by the license symbols represented in the below image. This license means that:
You let others copy, distribute, display, and perform your copyrighted work but only if they give you credit. You let others copy, distribute, display, and perform your work for noncommercial purposes only. You let others copy, distribute, display, and perform only verbatim copies of your work, not derivative works based upon it.
This protects the contributor's rights and also, protects the "owners" of the website from potential claims from contributors regarding improper control over works submitted via the forum(s); This should apply to images, "How to" descriptions, techniques and any item considered having intellectual property value.
