There was a request at http://forums.alliedmods.net/showthread.php?t=82916 to make a plugin for L4D to change teams. You don't really need one, just using sm_fexec <player> "jointeam 2 or 3" would work.

Here is a menu that does it for you:

	"L4D Team Management"
	{
		"Team Player"
		{
			"cmd"		"sm_fexec #1 #2"
			"admin"	"sm_kick"
			"1"
			{
				"type" 		"player"
			}
			"2"
			{
				"type"		"list"
				"title"		"Team:"
				"1"		"spectate"
				"1."		"Spectators"
				"2"		"jointeam 2"
				"2."		"Survivors"
				"3"		"jointeam 3"
				"3."		"Infected"
			}
		}
	}

You will need the sm_fexec plugin from http://forums.alliedmods.net/showthread.php?p=630439
