Michael has posted lot lists on this BB for a couple of our online auctions so participants of this BB could bid via email. ...didn't get much response.
As to doing the same thing where everyone with internet access could participate, I don't know of a chip related web site that has chat available. I don't know if Greg has thought about it for this site, but Rene appears to be looking at the idea sometime down the road for his site. We do have fun every Thursday night, and it's much easier to ask someone a question live than rely on that person seeing a BB post.
