FIELD SET WATCH

Usage: FIELD <field> SET WATCH [on|off]

When set on people will see changes to the field for everyone in their watch lists regardless of whether they are currently sharing any rooms.

Example:
/as field Comment set watch on

This can be used to send messages to people you are friends with. For example, you could create an away field that would notify everyone on your watch list when you switch it to away or back to here.
