If I were to use Vent, this is what I would need:
WCU Gaming
-CS 1.6
-CS 1.6 Admin Channel (PW)
-CS:S
-CS:S Admin Channel(PW)
-DoD:S
-DoD:S Admin Channel(PW)
-CZ
-CZ Admin Channel(PW)
-GG
-World of Warcraft
-Starcraft
-Guild Wars
And I would also need the ability for further expansion. I have this with team speak (users may also create their own channels) and I do not with Ventrilo.
