Actually, the network representative (or "supporter") would be... me. I volunteered for the position when one was needed, and everything indicates that I've been accepted. Only problem: Nobody has filled me in. At all. So I can just twiddle my thumbs and wait for someone in charge to pop by. Yay.
Good news though: Apparently, port 27015 is still open (HL happy admins?). So while I can't launch Steam normally, I can launch it in offline mode, then play on LM.
