If you are viewing this post as a MOTD then welcome, I am glad you found the server — enjoy yourself :)Anyway. This server can get lag-a-licious and from what the Steam server list says: its the only one in Australia so if your not from Australia it may be an idea to contemplate your ping ;-)
If yout not viewing this as a MOTD then I can link you to the guide that will allow you to play Goldeneye Source, all you need is a source based game on Steam to play such as Half Life 2 Deathmatch. http://www.goldeneyesource.com will be able to provide you with what you need to get started
More specifically, take a look at this page for a tutorial to get you started. You should also note that the server is currently running Beta 1.1 of the Goldeneye Source.
