Ok, with everyone talking about voice coms I did alittle research of my own and discovered some things about the voice coms I hope this info is helpful to the peeps that want to use something for their clan.
Roger Wilco: rogerwilco.gamespy.com
While Roger wilco is a good program, it has some serious flaws. Sometimes it distorts the voices where you can't hear what is going on. It is good for 3-4 peeps on it however, the more you have on there the more of a pain it becomes. Especially when everyone decides to talk at once you can't understand what is going on. ALso, it has an annoying little sound that is kind of hard to describe. The best description I can give is it sounds like a walky talky turning on and off. I give RW ***
TeamSpeak:

Teamspeak is a excellent program. With the exception of TS2 to me, that program just plain sucked! the 1.5 version to me is WAY better. Also, you will notice that ther is hardly ANY LAG with the use of TS and you can hear each and everyone that is in it clear just like talking over the telephone. Unlike RW when you have alot of peeps in there, it won't over lap when peeps talk. Of course your best bet is to have TS not on autotalk, as that will take up alot of bandwith but use a button to talk. Also, there is no annoying little sound like RW has.
There is 1 critical drawback with TS however, for the peeps that are LAN connected, TS kinda kicks you from the host server without you even knowing it. On your comp it will say you are still connected while on everyone elses, it says your gone. Very annoying when yo uare trying to play a game and you ckeep disconnecting. They did make a patch for it though, but it didn't fix the problem. I give TS **** Better sound, Better quality.
