The "PMS Buddy"

What on earth is this? A PMS Reminder to help friends and family understand when and why you might become irritable at a certain time in the month, apparently. Looks like talking about PMS is so taboo that internet applications are encouraging us to keep virtual tabs on one another to avoid having "dinner plates being hurled across the room", as we're told by the folks behind this proposed solution. Seems kind of lame to me.
