[O] Appt - How to quit displaying notifications?

[Nathan Neff]

Hello,

I'm using org-agenda-to-appt to warn me about upcoming
appointments.  I'm fine with the default warning time of 12 minutes, but
I would like to turn off the subsequent reminders that happen every
three minutes.

I'd like a reminder to occur 12 minutes before the appointment, then at the time
of the appointment.  I found the appt-display-interval variable which
is 3 minutes, but this is
described as "Number of minutes to wait between checking the
appointment list.", which is
not /quite/ the same thing as a "Snooze".

I guess I'll just send the appt-display-interval to 11 minutes or
something like that.  Is that what
everyone else does to avoid getting appt messages popping up every 3 minutes?

Thanks,
--Nate
