For those in the TF2 scene, there is a new site being launched that acts like the L4D lobby system. If you are interested in trying the site out, send me a PM and I can pass you the private login information. The site is in the beta stage now, but they are working with Valve who have given them 48 official servers.
I'm handing out 50 over at
srcds.com, but I'll also give out a few here if you drop me a PM.
