day planner/scheduler program

[Alexander Kushnirenko <kushnir@pccmu1.fnal.gov>]

Hi,

I'm looking for a simple program (like plan) that would send me reminders 
about meetings and things like that (paying apartment rent in time turns out 
to be quite challenging for me).  I was using plan, but it's daemon can 
spontaneously stop working without no apparent reason.  So I'm about to give 
up on it.

Another nice feature would be ability to handle computer shutdowns, so that 
program figures some message was not send because of the shutdown and sends it 
later once rebooted.

Any recommendations?

Thanks,
Sasha.
