I posted a patch file here:
http://members.dandy.net/~fbn/hangman.diff.txt
Main changes were to create a msg bind to allow people to do
/msg botnick hangcust My Custom puzzle, added more of a helpfile, fixed a few bugs, fixed ugly colors, formatting and spelling errors, etc.
I have not figured out how the "hint" stuff was meant to be formatted, and there is an unused proc in the script "proc hangman_fake" that I have no clue about.. And obviously the scripts instructions were wrong, as typing "!hangman" does not start the game..
I wonder if this script could be considered abandoned so someone else could re-release it.
Anyway, the above changes work for me, although they're not pretty (I'd just as soon re-write the script, but...)
