Perhaps I'm missing something, but aren't there quite a few nudes already on this forum, outside of the 'Nudes' thread? Alt process, tiny formats, and I'm sure a few elsewhere. Unless you're going to 1) make a rule that all nudes must be posted in one thread clearly labeled NSFW, and 2) go through all the old threads and move/delete/rename all threads containing nudes, I don't see how this is going to be workable.

I personally have no objection to a nude popping up now and then, and more importantly my wife hasn't had any objections when it happens and she's in the room. As others have pointed out, nudes are a very important part of the LF tradition, both historically and with current practitioners.
