help gag

Usage: gag [<player>...]

If you do not wish to see anything that a player says or does, you can use
the `gag' command to refuse all their text until you `ungag' them.  E.g.

  gag poslfit
  You gag poslfit
  You are now gagging: connector_0 connector_1 poslfit

`gag' by itself lists whom you are gagging.
