ircbot.bak.4.py

# -*- coding: latin-1 -*-

#this program requires a slightly modified twisted irc.py that returns
#nick!ident@host instead of nick for joins, parts and quits.


#todo: users[nick] instead of users[ih]
#todo: draw rules http://www.chessvariants.com/fidelaws.html
#todo: better timing for reconnect tryings
#todo: chess takebacks?
#todo: a decimal expansion from .base that's too long will quit with flood. and why doesn't anti-flood work there?
#todo: add passwords to servers/networks?
#todo: fingerresponse and versionresponse
#bug: chad did aq and it added mine not his most recent
