Last week's poll brings competition to Ventrillo vs. Teamspeak vs. None. And although at least 2 votes didn't get in for "Neither, it interfers with the role playing aspect of the game" because it got up late, it looks like Ventrillo beat all options by a long shot.
TeamSpeak! [6 votes]
Ventrilo! [21 votes]
Other [1 votes]
Nothing, it's too distracting [3 votes]
What is this you speak of? [3 votes]
Neither, it interfers with the role playing aspect [0 votes]
