No I don't know when BrainTalk will be up. But if the software gets to Mr. Lester by the late date (Sept 5th) then I'd guess they could be up as early as next weekend.

Regarding the chatrooms...the BrainTalk chatrooms have quite a bit of folks on (see the link in my signature) throughout the day

The chatrooms I set up as a temporary refuge is very empty most of the time (which is a good thing).
