It is nothing fancy at all. I have a gaming group with 230 members in it so far. This is so someone can host a small regiment for no costs. You would get a channel and 1-2 subchannels that you can organize how you like. You can add passwords to the channels to make them private. You can also recruit from our group to your regiment.
