What program do you use for team meetings?

Steam chat mostly.

Mumble is where it's at.

Skype.
Best quality ever.
Zero latency(Checked with "pew pew" method in FPSs).

Beats any other software any day.
Except the big meetings. Vent then.

Skype, TS and Ventrilo are VoIP.

Steam :p

I meet up at school :P

IM ( Jabber ) since it's the only thing you can expect everybody to have. Me for example Skype, TS or Ventrillo simple doesn't work and so it is with many others. e-Mail is slow so only IM left.

Im not on a team.

icq or msn

Forgot steam, msn and real life options. And probably a lot more.

Mumble. Low latency, cross platform, extensible, and open source (can be built "into" games without internal VoIP!)

Steam and msn depends.

Mumle ftw!

I am not in a team. I am a Pig Cop, who works alone, following my own rules. I promise pain to all criminals.

Yes, i am too busy to post something that does not have anything to do with my avatar.

still no 64-bit support for skype, shame on you eBay Inc.

Skype and msn, although I never heard of vent before.... basically, what is it about? (please, don't post links... I do know how to google... I'm just starting a conversation here...)

Steam.

Steam chat ftw. I've been trying to get the gang to move to skype, but my brother seems to have a holy war against it...

Not in team, but i if i was, i would probably use Skype.

Mumble.

ICQ, Steam.

Steam chat for day to day, IRC for weekly meetings.

Steam

I use Ventrillo for any basic team chating

MSN and Teamspeak

Skype and Steam

xfire

xfire FTW

Skype ftw man

My team uses Live mes. and for a few guys, Steam for most chating, the guy that uses Steam is able to transfer files in other ways, but the file transfer feature makes it really attractive for a small mod like ours...

Steam and IRC.

Ventrilo. No competition.

Steam + Skype

Steam group chat

Google Wave and Steam, with a little bit of Skype.

Steam.

xfire :/

I'll try to be original - i'm using Steam and Skype -_-

We use Steam chat.

We have our own internal software.

Steam chat. But I dont have a mic, yet.

Xfire.
