Ignore

Syntax: Ignore list
Syntax: Ignore (name)

This command allows an individual to filter out a specific source of OOC tells
without resorting to going into quiet mode. Ignore list will display all
the players that have been set to ignore. Ignore (name) will toggle
whether or not an individual is being filtered and will work regardless of
whether that individual is currently logged in.

This will block both ooc and ic notes, though you may still get notifications
of them.
