ars technica has an interesting post about BigString an e-mail service that allows you to send self-destructing e-mail messages. This could be the answer for those unfortunate souls who send e-mails at 4:00 am after the bars have closed or who forgot to spell check before they hit send to that job prospect! Maybe Conrad Black is the behind this little operation... or should have been aware of it! Anyway, I've not yet tried it but according to the site, "BigString allows a user to easily send, recall, erase, self-destruct and modify an email after it has been sent." Further they describe the service as "Our unique “Edit Sent Mail” feature allows you to recall, erase, add or delete attachments and self-destruct your emails after they have been sent." ars technica says that it works by basically storing an image of the e-mail, on BigString's servers, that the receiver gets a link to and the sender can at a preset interval or on a whim have the e-mail recalled, edited and resent, or self-destructed. The service apparently also allows you to track the e-mail as it is opened and forwarded elsewhere. Interesting concept, I'll give it a try and chime back later on what I think.
