If you haven't already checked out this tool - do it now before you get to AU. It's an extremely powerful tool that will let you find others with similar professions, personalities and skills. Whether you're looking for friends or people to meet - this is the best place to do it at. You can send messages to others, post questions in the forums and build a contact list.

Login info is the same as what you used to login/register for your AU classes. I hope you find this tool useful!
