[rt-users] RT2 relationships

[Wozz]

Is there a message somewhere in the archives that explains how
relationships are implemented in RT2?  I'm looking to do relationships,
wherein I can resolve a parent ticket, and all the children tickets
are closed and children ticket requestors notified, or after all
the child tickets are closed, the parent ticket closes and its
requestor is notified.  I've been playing with the relationships, and I
don't see that they are doing anything other than providing a visual cue as
to related tickets.
