First, if you didn't add -console to the target line, go here.

	First, open up the console. Now, type in "sv_players" and hit the [Enter] key. Text should come up that looks like the picture.
	Now you're ready to ban/kick people. Let's say that alex is being a little ass hat. He's mouthing off to everyone, his ping sucks, and he's blue. No one likes the blue team. Let's ban him. First, find alex's number in the number column (in the picture, it is circled), then type "sv_ban" then a space, then that number and hit the [Enter] key. You will see a message saying that you banned him. Good job. He's gone from your server until you let him back in.
	Now, on to unbanning alex. To do this, you need go into the console again and type "sv_banlist" and hit [Enter].
	You should see alex's name on the list that comes up. Look to the left of his name for the circled number. Simply type into the console "sv_unban" then a space, then that number to let him back in. You will see a message saying he is unbanned.
