# <mhy> I often wonder if we should use NSA bot or something instead and get dinstall
# to send emails telling us about its progress :-)
# <mhy> dinstall: I'm processing openoffice
# <mhy> dinstall: I'm choking, please help me
# <Ganneff> yeah. get floods in here, for 600 accepted packages.
# <mhy> hehe
# <Ganneff> im not sure the other opers will like it if i oper up the bot, just so it
# can flood faster
# <mhy> flood all debian related channels
# <mhy> just to be safe
# <Ganneff> /msg #debian-* dinstall: starting
# <Ganneff> more interesting would be the first message in #debian, the next in
# #d-devel, then #d-qa
# <Ganneff> and expect people to monitor all.
# <Ganneff> i bet we have enough debian channels to at least put the timestamps in
# seperate channels each
# <Ganneff> and if not - we can make it go multi-network
# <Ganneff> first oftc, then opn, then ircnet, then - we will find some. quakenet anyone?
# <mhy> I should know better than to give you ideas
