OK, here's the reply I got from Bats1990 on the Creatus Maximus boards, (Bats1976 here on MC I think).
Well, it is relatively easy. You just need a computer with a recording program. We use Garage Band (that is only for MAC's though) although you don't need it, we use a sound board to power some better quality microphones.
If you use a MAC with Garage Band you can pump songs and sound effects through it....we have a PC hoocked up for that though.
You can use SKYPE to talk to others or over the phone. We ended up eventually buying a piece of equipment to hook up to the computer and pipe through the mics and headphones.
Then it's just really a host for the files.
If you need more technical questions answered I could probably get those answered by the guy in our group that handles that.
Any more questions, LMK and I can pass them along to get some replies.
Or you guys could send him PM's or messages through the forum's mailer, tell him I sent you.
