Cryptography
Polybius was responsible for a useful tool in telegraphy that allowed letters to be easily signaled using a numerical system (mentioned in Hist. X.45.6 ff.). This idea also lends itself to cryptographic manipulation and steganography.
1 2 3 4 5
1 A B C D E
2 F G H I/J K
3 L M N O P
4 Q R S T U
5 V W X Y Z
This was known as the "Polybius square", where the letters of the alphabet were arranged left to right, top to bottom in a 5 x 5 square, (when used with the modern 26 letter alphabet, the letters "I" and "J" are combined). Five numbers were then aligned on the outside top of the square, and five numbers on the left side of the square vertically. Usually these numbers were arranged 1 through 5. By cross-referencing the two numbers along the grid of the square, a letter could be deduced.
In the Histories, he specifies how this cypher could be used in fire signals, where long-range messages could be sent by means of torches raised and lowered to signify the column and row of each letter. This was a great leap forward from previous fire signaling, which could send pre-arranged codes only (such as, 'if we light the fire, it means that the enemy has arrived').

Yep. That's one of the many mysteries.
Apparently an anonymous member from 4chan contacted Frank at that email address and said.
"So the antichrist has an Australian email address huh?"
To which they got the reply "Would it make it easier if the antichrist had a physical location..say.. somewhere.. Down under?"

So how would the polybius code work?
Translate the above sentence.

This is a screwed up site, but very interesting, and I want to proceed...so let me enter the freakin' password!
Any help?
