!remove removes yourself from all games you added
!remove <game> removes yourself from the specified game (multiple possible) and leaves other games untouched
!who looks who is added
!who ctf looks who is added for the CTF game (works with any gametype, or in combination like with the !add command)
!promote to encourage other people to !add up.
