We used to roll with no Trics. But frankly even before we implemented that rule trics didn't impact the games that often. If you're quick enough you shouldn't be worrying about trics detonating on you.
Also trics can vape the shooter now too.
Adrian, to subscribe to a channel there's a little people icon at the bottom right of the chat window. click on that, chat settings. It will bring up a window. Click the second tab in the window, and you'll find a box with "join/create" on it. type in shuttle_wars and then hit join.
To switch between chats, just click on the little arrow on the bottom left and it will bring up a list of channels you are subbed to.
Oh... shuttle_wars. Maybe I'll be back for that. If it cooincides with a new FE as well, it should be likely I want to be online anyway. No promises, though. Especially since I still haven't calculated how late it will actually be in my time zone. :p
