Analysis of IRC Code / Small Update

I've updated the Cipher Formats page to include the new IRC code and have added a new poll to the right-hand side toolbar.

In regard to the code, I've done an analysis in my cryptology tool--the top ten choices are as follows, listed in order from most similar to least similar:

Running Key...........0
Digrafid................1
Vig Slidefair...........2
Nicodemus.............3
Trifid...................3
Gronsfeld..............3
Vigenere...............4
Quagmire2.............4
Quagmire3.............4
Portax..................4

Of course, it's entirely possible that this analysis is inaccurate if the code is actually composed of two ciphers rather than just one.
