This new site to contact new gamers is awesome its called "meetups"
http://www.meetup.com/tour/
I just used it to find D&D players and Magic players in my area !
I also made a great format to gather wargamers old and new ,we just had a lot of locals go to college and we also have alot of new people going to college in the Manchester NH area and found players looking for a new place to go to game at ,so this site should help!
