If I chose 16 it would be $64 a month for a private server. If we did that, I would ask for a little help on that. And from reading the FAQ, it says the Admin can have control over what map can be used, rotation period, and whatnot.

So there's what I see so far. Looks pretty painless to setup. Less then 5 minutes and the server is running.
