I thought about it, but those are typically such separate communities that they'll probably want their own sites. If people really think that LispForum should cater toward anything Lisp-like, we can easily extend it to do so. Even if Scheme was included, I'd think that Emacs Lisp would probably be a stretch. If you really want to talk about Emacs Lisp generally, you could do so in the Emacs forum on this site and I wouldn't mind. There's crossover there, so just do it and we'll see what happens.
