Hey, I've been playing Guildwars Prophecies for about a week now and I feel that with a bit of knowledge I can ask a few
semi-intelligent questions. "Semi" being the qualifier here.

I'm still in Pre-searing, and I'm going to take on the quest that switches you over today.
One thing I noticed from the beginning is other players wearing capes. Now from what I understand these are guild capes. Er... uh....

How do you get these? Do you wait until someone asks you to join their guild? I've seen new levels wearing these capes, so it doesn't seem to be based on levels. How does the whole guild thing work, because it hasn't had anything to do with the game thus far? Every so often I see a message on the left bottom of my screen that says Such-And-Such team won in the Hall of champions or something like that.
The quest, adventuring and killing monsters part I get, but the 'guild' part I definitely don't.

Sorry if this is a monumentally stupid question.

P.S. Where can I find red dye? I found in the Wiki that I should kill Stone and Hulking Stone elementals, but they're not dropping dye. Unfortunately, I'm not getting xp off Stone Elementals any longer.
