Ohh okay thanks for letting me know!

No worries you didn't bother us, me and my friends actually thought it was funny that you just kinda showed up LOL. If you ever wanna play l4d we could, but we were just wondering who you were ^^ We had a good laugh about it. Take care Cafe

In fact, simply press the "~" key on the keyboard to bring up the console to enter commands
Type "openserverbrowser" to find a list of all servers, including yours servers
So I guess "Friends only" just hides the server in match mode, but still shows up in the server list.
Because the servers in China are so chaotic, I just joined a random server. I'm sorry if I bothered you
(My English was poor, so I used a translator.)

How'd you join us in l4d2? I thought I had it set to friends only, but then you just, appeared.

Or maybe I was being silly and forgot to do that

huh？

Talk to me Cafe
