Burn Note Offers a Safe Way to Send Passwords

This note will self-destruct after you read it... Okay, so that's not true, but if this note was written on Burn Note it would be true. Burn Note is a free service for sending messages that self-destruct after they are read by their recipients. To use Burn Note just visit their homepage and start typing your note. When your note is complete a unique URL is generated for you to share. Once that URL has been used by someone else, it no longer works.
