I remember the first time I found out about this site a few years back. It was pretty much the only website of its kind, filled with great content, real users, and a superb layout. I believe there has been several wanna be rip-off websites who attempt to emulate your presence, but none so far have held up to this sites extrodinary standards. Kudos to the team!
I've tried thinking of better ways to market your site since I am an internet marketer, but I think your just fine (: Thanks for providing a very valuable service.
