well why don't you start one?
So how come there isnt a k12ltsp irc channel? heh. Mailing list is nice, but realtime yacking is handy.
Really, All you have to do is connect to your favorite server (try freenode) and /join #k12linux or something, and it will create the new channel. I'd stop in when in the neighborhood.
