It is my understanding that copyright to everything in Wikipedia belongs to the contributors, who are releasing it under the GNU FDL.
I thought *Bomis* released *the contents of Wikipedia* under the GNU FDL, in any case; so then each individual contributor first must release their contributions to Bomis under the same license? This seems to be what several of you have been getting at.
I think the safest thing would be to clarify so that it says the various authors own copyright. The rights granted by the FDL are supposed to be enough for everyone who wants to use the encyclopedia, so why not Bomis et al...
If copyright "had" (I suspect somebody would fork to a degree) to be handed over, it should be to a non profit organization.
I think this is very important.
