When I contacted one of the birthday people on the list...they told me they received the message more than once.

David increase the $estimated_load value.

The very high trafic of your board and very low estimated_load number (compared to your traffic) causes it. This is how it happens:

One visitor triggers the hack at midnight, the hack begins to compile birthday greetings but before it finishes and updates the database date, another visitor triggers it again (the first visitor's trigger didnt finished yet, so database date is still yesterday). Hack will be done in less than a second and your traffic is so high that, it gets triggered more than once in that very second and produce more than 1 greetings.

With so high traffic you really dont need so low estimated_load value. Increase it and you'll be fine.
