Just saw the comic, and felt so proud of myself for deciphering it. I shoulda known somebody would've gotten to it long since. :)

I love cryptograms. (It's not an acrostic, btw.)

Just so you know, Rich, apostrophes make for a really easy point of entry for these things. There are very few letters that can follow one, and not very many that can accompany one period. What's more, they're some of the most common letters. The letter "F" is also a dead giveaway.
