SETSUMMON

This command allows you to restrict who is allowed to summon you.

Syntax: setsummon  - shows a list of settings
        setsummon <number>
        <number> is 1 through 6 to toggle that option

Example: setsummon 5 toggles whether members of your formation can
         summon you.

Just because someone does not use this command does not give a player
the right to summon anyone against their will. Anyone caught doing
this will be punished appropriately. Summoning without permission is
illegal.
