A personal web-based assistant. Notify her of an appointment or something you want to remember by email. She will notify you of appointments 15 minutes before they start (by default) by email or text message.

You can search your messages by topical tags (ie - @Birthday, @yearly, @family, @work).

You can also update it using Jott: (http://jott.com), allowing you to update your calendar by talking on the phone.

Great for someone who wants phone notifications of appointments but doesn't have a smart phone.

Will notify people of the same appointment if you CC Sandy on an email to that person, even if they don't have an account.
