This is a website that allows you to post "sticky note" messages on a wall for everyone to read.  To post a message, just click on the "Post a sticky" link at the bottom of the green box.  A new tab or window will pop up and you just have to double click anywhere on the wall to add your own message.  NO SIGNUP REQUIRED, but if you don't sign your name, I'll have to delete your post!  To see your sticky note on this page, you'll have to refresh your browser window. 

Enjoy!  (And keep it clean--we're the respectable generation now!)
