I made something very similar to this, but less features.

I was looking for something to just remind me of something at a given time.

I'm currently using it to remind myself of things to bake on Saturdays, but I've used it for a lot more than that.

Right now you enter in What, and when, then it emails you at that time.

I've been meaning to add recurring tasks, and I like the idea of "nagging tasks"
