I've been playing for a bit off and on, but I'm only finally in the levels where the main story line is requiring that I dungeon dive with a "Light Party".

I've gone through 2 of the 3 dungeons, and (as I sit in front of the last dungeon waiting for the duty finder to tell me people are joining) I can't help but wonder...
Exactly what is the etiquette for dungeoneering?

Am I supposed to /shout for people to join? Do I just wait patiently?
I've tried asking my peers in my server, but no one will tell me.

Apparently this is too n00bish of a question?
But, truly. What am I supposed to do? I don't want to be "that guy" who everyone goes on about who plays like a douche... I'd like to know how to make the most of this game so that I, and everyone I come in contact with, can continue enjoying it.

At the very least, if someone could direct me to a place that explains dungeons in more detail, I would be most appreciated!
