------END GEEK CODE BLOCK------

This is not just your stock "Geek Code" block. The last line of the block sports the "Geek Code Weapons Extensions", of which a description can be found at http://kuoi.asui.uidaho.edu/~kamikaze/documents/geekWeapons.html.

The stock Geek Code block can be decoded via a web-based form at http://www.ebb.org/ungeek.

Just use the web-based decoder to decode the whole block, and then look up the last line's worth on the "Weapons Extension" web page. The web based decoder will just ignore the extensions.

Happy decoding.
