Could someone list the methods of talking to others across games?

Like, how does the green text appear, etc...

It would be helpful for not only me, especially in the state I am in right now, but others that are not so aware of how communication can work while playing Diablo.


And a look at that wand would be nice.

I'm on at eoffnm/trout


NOTE:

If ANY of you find ANYTHING to Trang-Oul's set, I'll do anything to get it. It's the perfect set for what I want.

Here's a link to what it is:
