Many open source projects have live discussion channels (often via IRC) and I think they can help encourage strong and nurturing of communities, as I'd like the GWTP user and developer communities to be.
Following a suggestion by Arthur Kalmenson, I checked out Convore and it seems like a perfect tool for such a channel. I therefore invite you to join us over there for quick chats and preliminary design discussions. Complex questions should still go on the forum.
(Disclaimer: this is an experiment, we'll see how it goes... Also, the channel may not be manned at all times.)
Cheers!
