The chat program we were using was kinda buggy and eventually was removed because of that and other problems. I may bandaid it and put it back up if I come across some new info, it's a long story...
I've added a chat option to the Bulletin Board itself. You have to scroll down to the bottom of the main page to see it.
Eventually I'm going to make a new chat program, as well as other cool stuff for the site. All I need is TIME.
Unfortunately, I've been extremely busy for the last couple months and I haven't had as much play time as I would like.
