Dave, here's a recent thread about future chats, from January.
In case you don't want to read that rather lenghty thread, here's a quote from Ron near the beginning of the thread:
Actually, guys, there probably aren't
going to be any more live chats.
Unless they figure out a better client to use, right?
I have friends who brag about being able to create chat clients over a weekend. Wouldn't it be possible for someone here to do the same? That is, create one over a weekend... I'm sure we could tolerate some bragging as well if it turns out well.
