"In addition, all text copied from Wikipedia is released under the GNU Free Documentation License (although you still can't use it for commercial gain)." — you can't do that. If it is licensed under the GFDL, it licensed is under the GFDL, and so may be used for commercial purposes in accordance with that license. Just because it is also licensed under CC-BY-NC-SA once you add to it here (which does not allow such use) does not change that fact. You should also be careful not to add GFDL content to existing CC-BY-NC-SA content as the two are incompatible (you can't go CC-BY-NC-SA -> GFDL since that adds commercial rights to previously non-commercial work). --GreenReaper(talk)
