I use Yahoo calendar for a whole bunch of stuff / reminders - one of them being heartworm. So, every month on the 30th - I get an email reminder (to my hotmail address) that it's Heartworm time on the 1st
! I also have all birthdays and other events set up at Yahoo calendar too. I like Yahoo bc when you set up an "event" or a "reminder", you have so many choices (as in, send the reminder 14 days before or 1 day before etc) and "repeat" event.
