I was going to right a post about a new online tool, Sandy, but Gearfire has already done it. Sandy is a personal organization tool that allows creates reminders and to-do lists and then will email them to you, so you don’t have to remember. As Gearfire concludes, this would be useful for students or people who want an easy way to stay organized. For me, what little I tried out of Sandy, didn’t exactly fit with how I like to organize everything. But it might be the right minimalist, online sticky note solution you are looking for.
