So Discord is a free VOIP.
You can download the program or you can connect to it trough your browser.
What makes Discord popular, other than it being free, is that it supports chatboxes. Basically different channels in which you can type, and the messages will be stored there for a long time. So say you don't log on for a day you will still be able to read what was said when you were gone.
It's nice to keep contact with people and casual gaming. I don't recommend it for serious gaming (like if we were to play an MMO together TS would still be better).
Anyway vote on the poll and we can get one running if it's worth it.
Edit: the poll doesn't allow me to capitalize "I", its tilting me :D
And I also can't edit "don'tk now". I probably shouldn't be doing this at 2 AM!
