It needs a buzz button like instant messenger. ha ha, I opened it and left it on the other day, 2 people got on and then back off, because I was off reading.
LOL Slick! I remember that because one of those people that came in and then left was me! Â
I go in fairly often to find no one there as well, but I always just think it is me, and that you guys hide when you see me coming!  Then when I leave, you all come out and talk about me. But, hey, those are just my personal issues!Â
I think it should bark at us to let us know when someone is there...
