Just got home a little while ago, and have been thinking about this some more. I was thinking about somethiing someone had mentioned in chat a few days ago, gematria (
http://en.wikipedia.org/wiki/Gematria ), and I was trying to think whether that might have something to do with it. I don't fully understand the gematria thing yet, though.
I was also thinking about ottendorf ciphers, but I think that would be presented differently.
I'm still thinking about it. Be careful out there, Grey. Check in and let us know you're alright now and then, and if you hear or think of anything that might help, let us know.
