I keep this site open on my lap top all night while I'm watching tv going back and forth between here and gunbroker and ebay. I think a chat room is a great idea.
I also would like to see a chat room, but are we actually too big to have one? We have many, many members here online all at the same time.
I've only been on a few, and all were interesting and informative, but too many made it a little confusing. We would sometimes have 3 conversations going on at once, and these were at much smaller places.
