In the corporate world, senior managers have an executive assistant to manage their calendar and help them stay on track of their to do list, and home-based business owners often hire a virtual assistant to do this for them. But what if you don't have an assistant and it's just not in the budget?

Meet Sandy – the personal assistant who works for free!

When you "hire" Sandy, she gives you her email address and then, whenever you set up an appointment by email, you send her a copy, and she'll email you with a reminder! What's really cool is that it's not limited to appointments – you can email Sandy any kind of reminder, including birthdays, tasks, errands, and even websites and blogs you want to keep track of. It would be a great way to keep track of sites that don't have an RSS feed, like this blog!

You can also:

• enable a private iCalendar feed of your reminders, appointments, and to-dos, which allows you to subscribe from and synchronize with your existing calendar system
• arrange to have reminders delivered to your cell phone
• connect your Sandy account with your Twitter account
