Hey hey, kids. Being the absent minded sod that I am, I'm after some notifier software that will hide in my system tray, and pop up message boxes at time I can specify. Eg. "Tuesday 10PM. Take out the bins, you useless git." Any suggestions? I prefer it if it were freeware, can handle messages that occur when the PC isn't on (maybe dump them after a certain amount of time?), and is as unobstrusive and lean as possible.
