Leaving A Guild?

I accidently joined a Guild and do not want to be in one. How do I quit or leave it?? Also, when other players say PM me to trade ect... does this mean click on their name and whisper them??
Thanx For Any Responses

1. Go to your guild screen. Next to your name, click on the dropdown menu to the left of it. Select the option, Leave My Guild, and confirm.

2. Yes, PM = Private Message, which is the Wisper in the case of Guild Wars.

Wisper... I think he's the Mesmer boss in the Maguuma Jungle
