+# <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
