If you guys don't want to talk, it's not a big deal. You can go into the "text chat only" room so you don't have hear to people talking out loud. Usually 90% of the discussion is in the chat box, anyway. From there, you can either lurk, or slowly get used to interacting with the people who frequent Ventrilo. Right now, there's probably about 11 people on, and none of them are talking out loud. Only about 4 of them are even participating in type-chat.
Come in when I'm around and I'll try to help you out in any way that I can.
There are some obnoxious people sometimes but you can always just switch rooms or put them on mute. It's pretty easy-going.
