We used to have the Shoutbox but we get a lot of traffic so it overloads the Shoutbox and causes problems with the site. We've been working on some ideas for chatrooms instead of a Shoutbox though.
http://8wayrun.com/chat/
works great regardless of traffic.
it is a xenforo mod, but there is something quite similar for vb4. pm me and we can talk more if ya guys are really interested, though i'm sure STORMS is already looking into it.
also, on topic; i made the 'mistake' of calling MKU a site for casuals and what happened? they threw their best at me on PSN to prove me wrong. now i have steady, good competition. i've learned that regardless of the site content, there are lots of good players there, and the shoutbox is the easiest way to quickly find competition and avoid the scourge of garbage that is the general chat rooms on psn/xbl. i'd LOVE to have an active embedded IRC channel or javachat or something similar here at TYM for quick matchmaking. that is the one thing that would truly set TYM above the 'competition'.
as a quick solution, i've set up an IRC channel, #testyourmight, through geekshed, which is the server we use at 8wayrun. you can use any IRC client and joining in it is simple;
1: connect to server; irc.geekshed.net
2: enter command; /join #testyourmight
and bam, we have a chat room.
