How to start your own lobby.
1. Enter a gamemode and select the lobby option.
2. Set the lobby to public
3. Witness the people that join 2 quit.
4. And pray that you win the lottery whilst yo wait like a dumbass.

Why do people join 2 quit?
Because they want to play in a match rather than lobby.

Why do people eventually leave a lobby?
They get bored waiting for it to get full. However it would help if join 2 quit users stayed as everyone benefits.

If you are a join 2 quitter please stay in lobby's and stop ruining the game for everyone that patiently waits :3

We are here to play left 4 dead 2, not join 2 quit simulator.
