I keep reading threads with games on Steam and we all have our Steam names listed, but we don't have an entire list compiled..
I figured it'd be a good idea to do one massive thread where we can find everyone.
To find yours, right click the Steam Icon on your task-tray, and choose Community.
It'll bring you to your "Home", and you'll see the address at the top.
Copy that and paste it here.
People will then be able to find your Steam page and add you to their Steam if they so choose to.
