I've seen a couple of references to "If This Then That" software, but I don't really see how it would work for this purpose. I might have to write some sort of script with a resettable cron job, I guess. I was hoping for something with a spiffy GUI, which isn't something I care to learn how to do.
I need something that will automatically message people (via email, text, or whatever) various things upon my demise.
