Did...did you use "then" when you should have used "than"?Maybe I'm wrong...but am I really out-grammaring you?
(Also, I thought the Hitchhiker's Guide app was a cool idea! And since it's free, I'd try it for the gimmick.)
... Um... It's properly spelled "then" in cases like this, where it's, ah, in the subjunctive episcopal case. This is also why "friendly" was spelled with a semicolon.
