Improved Bomb in a Letter..

Do you hate someone with your all guts and want to send a threat to them, but is scared because it's evidence that could very well be possibly held against you? Or simply, kidnapping made easy with kicknotes with its self destructive notes that you can send to anybody and watch it blow up in your enemies' faces, MUAHAHA!!!

Basically, the note expires and dissapears sometime (changeable) when the receiver has read the note or opened it. It's funky self deletion makes it convenient to send anything even during work. Which you can fully exploit.

The site says:

Use kicknotes to send:

• Sensitive messages
• Personal contact info
• Announcements
• Invitations
• Temporary Advertising
• NSFW links
• links to music
• links to images
• links to software
• links to anything
