we already had a discussion about implementing a chat box and it was decided to be a bad idea because they reduce forum activity.
the thread is here http://www.dbocom.com/forum/showthread.php?t=282
also in the future put your suggestions in the suggestion area so i am going to move this thread over there and close it because it has already been resolved.
You can always go on ventrilo, the same one we use when DBO Beta.
The activity is less atm because there is no beta, but there are still a few people chatting.
If you don't got a microphone u can still use the chat on it
