Most people in South Africa don't use Left 4 Dead's lobby system because it often selects an overseas server when you start the game. Instead, players usually connect to servers directly, which makes it a bit more difficult for a bunch of friends to start a game together.

However, there is a way to force the lobby to select an SGS server. You need to use the following console command:

mm_dedicated_force_servers

This command allows you to specify a list of IP:port addresses that the lobby can use. Each IP:port address must be separated by a comma. A good way to set this up is to create an autoexec.cfg file that contains the command. Here's how:

1. Navigate to this directory (or equivalent):
C:\Program Files\Steam\steamapps\common\left 4 dead\left4dead\cfg

2. Create a New Text Document and rename it to autoexec.cfg

3. Open the file, put the following line into it, and save:
mm_dedicated_force_servers "196.4.79.65:27015,196.4.79.65:27016,196.4.79.65:27017,196.4.79.65:27018"

The IP:port addresses you see there are those of SGS's four Left 4 Dead servers. You can add other servers in there if you like. Please note that the lobby will most likely fail to find a dedicated server if all of the servers in your list are already in use. Additionally, two of SGS's servers are set up to only allow for Versus mode.

For your convenience, here's a list of SGS's Left 4 Dead servers:

-= SGS LEFT 4 DEAD I Server =- (196.4.79.65:27015)
-= SGS LEFT 4 DEAD II Server =- (196.4.79.65:27016)
-= SGS LEFT 4 DEAD VERSUS I Server =- (196.4.79.65:27017)
-= SGS LEFT 4 DEAD VERSUS II Server =- (196.4.79.65:27018)
