Hey, Imega. At this moment in time the only active guild that i'm familiar with is my guild, the Ember Adventurers Club. Unfortunately we're closed to new registrations at the moment.We're a really laid back casual friendly guild dedicated to giving folks a place to get to know each other in a friendly, respectful environment. I'm sincerely hoping to see someone start their own guild based around the same concept. The more guilds the merrier! It's just that i'm new to this whole guild leader thing, and 60 or so people is a lot of people.
That being said, if you decide to take the proactive route and start your own guild, I would be more than happy to share what i've learned since starting my own endeavor into guild leadership. It's not really that hard, the trick is finding awesome like minded individuals why share a similar goal-the desire to hang out in a laid back environment with cool people who enjoy a variety of games with people they've come to know as friends-and listen to them, because the odds are pretty damn good that if you're lucky enough to get a good group of people they'll want their guild to succeed just as much as you do.
Good luck! Oh, and welcome to the forums ^_^
