I created a group about this on facebook and the link is here: http://www.facebook.com/groups/135659763186064 

Look at my first post and I explain everything about when and why I did it, there. Right now, we're coming to a consensus around "anime-jin" (lit. "anime person") and I put forward that and another phrase used to describe us (in the comments in the first post for the latter) but does anybody else have any better ideas?
