i knew I should have explained this a little better.
You actually tell us the statement, and we have to figure it out.

But if anyone wants to try it that way, go ahead. Just post what the key is (try to be very descriptive) after a fair amount of time. So it could be a couple hours, ten posts later, but the maximum is 48 hours after you posted the encrypted message.
Provide hours of fun and boredom fillers.
For fun guys, so don't get angry or whatever.
Fun, key word.

This is what it looks like when a Dvorak user tries to type on a qwerty keyboard.
