Somehow I totally misjudged the amount of time this would take, then lost it. I saw someone doing a spell checker that read in a bunch of English source materials to build a probability table for words, so something like that might work for letter pairs as well. I'll have to give that a try! Cool, thanks for the advice. Somehow I totally misjudged the amount of time this would take, then lost it.

P.S. Happy hunting!!
