The TagYerIt password is specified in TagYerIt.ini. TagYerIt options can be set in the TagYerIt.ini file or by a console command interface. The default options seem to work very well, although they have not been tested for more than 10 players. Note that you can create very different games of TagYerIt by changing the options. These commands can be executed on the game's console or by any client.
Most options are fairly self-explanatory.
Minimum number of players needed for a game. Maximum number of seconds someone can be It. After this amount of time, someone else is chosen randomly. Maximum number of frags someone can get while they are It. If they reach the max, they receive a FragLimitBonus.
