Windows 7 Tip: 
MailFreezr.com is a “freezer” for email messages for a period of between 1-100 years. You can have your message delivered in a year, or up to 100 years from the date of creation. To send a message, simply fill out the fields provided as you would for any normal email (your name and address, the recipient’s address, the subject, and the text body itself). MailFreezr is a free service, and no registration is required.
“MailFreezr.com is a service, which saves your email and will deliver it to your recipient through given number of years.
Imagine yourself, how would be pleasure for your folks to receive the message from you written a hundred years ago, when you will in the world beyond?
Write about your feelings, declare your love, confess in something, what you afraid or don’t dare to tell now… Just anything”.
Why would anyone want to freeze their mails? lol How about sending a love letter to our girl friends and freeze it for the next 20 years
