How to send messages that self destruct

Privnote lets you send electronic notes that self destruct after being read. What makes Privnote different from sending a regular email or instant message?

• You get a link to the note, and once that link is clicked the note is destroyed so it can only be seen once. If someone intercepts the link and sees the note before the person who's intended to read it, that person will know that the note has been eavesdropped, and can tell you about it.
• If you want to be notified when your note gets read you can do it by checking the notify box located below the note. Neither email nor instant messaging provides a reliable way to know if, let alone when, your messages are read.
• If you send a note and suddenly regret having done so, you can click the link yourself which will destroy the note and prevent the receiver from reading it.
