There is a command line program called remind that is available in the macports tree. Couple this with the tools that OF has for sucking actions out of email.

Remind has a rather arcane syntax in the reminder file, but you can do things like "Remind me 3 days before the third Sunday after the second full moon after the Fall equinox" First Thursday, and last Monday of the month aren't bad at all. The documentation has a ton of examples. Install the program, add an entry to Cron for it, and edit your remind list.


AFAIK remind's code is under either GPL or BSD license.

Since this sort of reminder isn't needed very often, it may be easier for the Omni Group to have it as a server, and you log into a web site and have a fancy GUI for creating and testing events like this.
