I leave myself a lot of messages from my cell phone to remind myself of stuff when I get home. Now there's a service that allows you to do this and organize the results. It's called braincast.

With braincast, you call a toll free number and leave yourself messages. You can then set it up so that you get email messages about your reminders. It also stores messages, allows you to create RSS feeds (which you can share), and lot's of other cool stuff. braincast is definitely worth checking out.
