Do you wish to send an email to someone on 1.1.2010? FutureMe is a novel concept which allows you to send emails in future.
FutureMe has a neat interface to send an email. Specify the email address (ensure it lasts long enough), subject, message and the date to be sent in the future. You can also keep the email private or as a anonymous public one. Click ‘Send this to the Future’ and you are done.
