I like your Tutorial/RFC. I wrote two bots lately, and some of my work would have been easier if I had such a comprehensive collection of links.
I haven't read all your links, but something seems to miss: there is now description of how to handle different charsets in IRC. This is something that can be a pain to handle, and the documentation mostly ignores the issue .
Net:IRC and POE::Component::IRC don't mention it, Bot::BasicBot offers to set one possible encoding, which is not always sufficient.
Also I did try to write a logging script with irssi, but I couldn't find a reference manual for Irssi.pm. If there is such a documentation it would be worthy to point to it directly, maybe I'm not the only one who is too dumb to find it.
