why not?

I thought this was that forum.
This isn't a therianthropy website (at least, not since I last checked), it is a Werewolf fansite.  This forum was created specifically to deal with the therianthropy topics that were interfering with the fictional-werewolf chatter.  Really, I think if you really want to talk about therianthropy, you should go to a site that actually caters to therianthropy.  This site isn't bad, but there are only a few people here with any real experience on the matter who are greatly outnumbered by people who are asking for more info and advice, where as a site like Weresource, Trueform, or even Werelist has a strong backbone of articles and other resources and a community filled with experienced/knowledgeable users who have been awere and talking about this for years.

That's true too, the name would be ambiguous on a non-therian site like this one.  People don't come here for Therianthropy, they come here for werewolves.  Why should a forum that isn't about werewolves be put up?  If you can get popular demand for it, like with this one, then I'm not going to oppose that, but shady howl has made a good point: it's just going to be mixed in with the fictional nature rest of the site.
