Ever have trouble remembering important dates? And how about less obvious things like checking to see if you ever received that mail-in rebate you so carefully completed all the forms for? I do - and have just discovered Memotome, an internet service that emails you with dates you have registered just before they become due.

Perhaps the best thing of all about this reminder service is that it’s free. With its potential for saving you money, it has to be one of the best ideas in a long time. I have tried the digital diaries that sit on your computer, ticking away until the appointed dates - but my problem is that most of the time I don’t have them running in the background. And, if they’re not running, they can’t remind you.

But everyone checks their email at least once a day and this is where Memotome scores. Have a look and see if it could be helpful to you: Memotome.
