I got into the Quake Live Beta a few weeks ago and have been having quite a bit of fun with it. For those that don't know it's basically a free version of Quake 3 Arena running solely through a web browser and all the matchmaking and player stats are run through the website. It's really good, you just create a free profile and start fragging away. It's all free, but it's in closed beta at the moment. You need to be invite to get in. I've got 6 invites to give out. So the first 6 people to post in this thread that they want in will get them.
