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