Step 1:
Mention your desire to leave to the Guild Master. He may find you to be a valuable member of the team and try to work things out in your favor.
Step 2:
Type "/gquit" to leave your Guild if the drama becomes too great and you must leave.
Step 3:
Look for invitations to join another Guild. The World of Warcraft Guild recruitment forums are one resource for finding a new guild. By looking at some of the linked guild sites, like http://www.ugamegold.com. You'll be able to gain more of a sense of the guild's membership and find one that will be a better fit.

Great post and source article. I grew up in the same small town as “Randy Travis: Country Music's Finest,” and on my last visit was able to see a house my family built in the late 1700's. It still had bullet holes from General Sherman, a scratched pane of glass from generations of newly engaged daughters testing their diamonds and, believe it or not, 200 year old corn cobs used to insulate the walls. I'll bet “history” is close to us, it's just hard to see. (Mammoth. Ha.)
