Since most people don't know this, most of our TF2 announcements and activity actually occurs in our other (private) Steam group: http://steamcommunity.com/groups/overclockedremix

If you leave a message on the OCR TF2 thread ( http://ocremix.org/forums/showthread.php?t=28053 ), one of the admins will eventually add you.

Also, this weekend is the Prop Hunt event on OCR TF2 RED: red.ocrtf2.com:27015
