[Scorpio]

I met people in classes and through clubs (Psychology association). I didn't have to meet that many people, just a couple of good ones and then I just ended up meeting all their friends and got absorbed into their social circles.

I also met a lot of people at a good job I had. I was a banquet waiter at a convention center near my school and there were dozens of other students working there.

Edit: Oh yeah, scroll down through the threads. The one called 'Good Social Skills Site' has a link to a site that focuses on what you're talking about (one of the articles is called How to get a Social Life).
