You'll find good people on your team here and there when you pug.  Friendslist them, try to play more with them.  Lots of people on here have ventrilo, people have also posted free vent servers you can play demigod on.  That's how premades get formed.  GL.

in game, shift - tab.  Click on friends, click add friend - type their name / click ok.  Takes a few seconds for them to appear.

Whenever you want to chat.. just shift - tab, click friends, find a friend online, double click their box and a private chat box pops up.  GL

There's a public ventrilo server you can use in that post (along with install instructions, etc) so you that you and whover you end up pugging with can use voice chat.  You'll probably be able to find some good teammates on there.
