on dot.kde.org, and also the kde-cafe mailing list.... this type of thing is cool for the kde comunity. you might want to trim down the number of forums tho, have a number like the gentoo forums.
I don't see why the number of Forums should be trimmed down.
But I also think that we shoulld promote this Forum wherever possible. I mean, hey, we got an official Forum now, so we should be bursting of users by the end of the week..
