Interesting comment I got the other day. It appears to be a sort of a trailhead for a substitution puzzle. Several keys were given to 20 different bloggers via comment. They lead to a website at http://aequalswhat.blogspot.com/ with a cipher to solve. The commentees need to get together to pool our clues. Shades of The Westing Game!
Unfortunately the guy who posted the comments has been spanked because people thought he was leaving them spam.
If you’re one of the other recipients of a key, contact me at the mail address listed on the right sidebar.
