It's a journal. But you don't use it to record your thoughts and feelings unless you want to, but you'd be informing the WORLD of your thoughts and feelings. Not many people like to do that.

You can use this to communicate with people. If you write the word 'locked to in the subject before someone's name, you communicate with them specifically.

It is pretty nifty considering they work without electricity unless you y'know have one of the journals that are electronic and run off electricity, but most people have the ordinary paper and pencil kind.

Pretty easy to figure out. But welcome to Chicago. :D
