I was actually about to pose this same question.
I'm not sure if Jack disabled it or if there's some sort of perplexity involved with it but it's a great tool for the MadJackers to be able to interact and get to know one another other than through what we post everyday.
A beer drinking chat sounds like a great idea also. I know some of the late night college b-ball posters would enjoy that also. Any help would be great Jack!
Thanks.
