In the console you can use these admin commands:
ADMINLOGIN <userid> <password> - Login as an administrator
ADMINLOGOUT - Drop administrator access (example: to vote for next map without forcing it)
KICK <playername> - Kick a player
KICKBAN <playername> - Kick a player and ban his/her STEAMid.
Once logged as an admin, if you vote for a map or kick a player using the map and kick voting windows, the map will be changed immediately/the player will be kicked immediately, no voting will take place. So please ADMINLOGOUT before you vote.
