I advise searching through the guilds. Find one to suit your interests and join in the mini community there. It might be less daunting, and more focused on something you know you like, than the site as a whole.
There's so much to do on here, it's hard to choose sometimes. Perhaps play some games to earn gold, or post on the forums. There are tons of friendly people out there. You're sure to make friends along the way-- and don't hesitate to ask questions if you're curious about something. 3nodding Hope you have fun~
