Got a secret message to share with someone? Check out Privnote.
Privnote (short for Private Notes) is a simple web service for creating web notes that self-destruct or become unavailable as soon as they are read.
Type a text note in the space provided and you’ll be provided with a one-time use hyperlink that you can send over an IM or email message. Once the link is clicked, the associated text note is deleted forever.
There’s a read receipt option if you like to get notified as soon as your web note is opened by the recipient.
