MMOCircles has launched into open beta with players around the world invited to join up and find like-minded players to adventure with. So far, you can join others playing Vindictus, Neverwinter, and Hellgate. You can sign up on the MMOCircles site or via Facebook.
You can sign up using your personal email account or via facebook. It’s totally free and you can join a clan, message your friends, and post on your own wall. The website is currently in beta so more features are currently being added to the site as it grows.
Check it out on the MMOCIrcles site.
