We have a seperate domain, and some infrastructure is being set up as-needed, like bugzilla (bugs.nemomobile.org). My personal feeling is that I don't think seperate forums will happen, though: there's too many already, and right now, we don't have much of a userbase, so it would be a lot of tumbleweeds rolling around.

Of course, there is always a need to 'accelerate' - but moving to a ghost town won't really help that much :-)
