Ftag

Freeze Tag games start automatically every so often. To join in a game of
freeze tag once it has begun type FTAG. You will automatically be placed
on either a Red or a Blue team. If enough members join, a game will start
and all players will be placed in a random room. The object is to then
TAG all members of the opposing team. Supposedly once all members of the
opposite team have been frozen, a team wins, but this doesn’t always
appear to work correctly. You can also TAG members of your own team to
un-freeze them and get them back into the game.
