Code:
on *:text:!*:#yourchannel: {
  if ($2 == $me && $ini(mycommands.ini,me,$1)) {
    describe $chan $replace($readini(mycommands.ini,n,me,$1),#2#,$2)
  }
  elseif ($ini(mycommands.ini,$1)) {
    describe $chan $replace($readini(mycommands.ini,n,$1,$rand(1,$ini(mycommands.ini,$1,0))),#2#,$2)
  }
}


Then, include a new section in your mycommands.ini file:

Quote:

[me]
!taco=eats some tacos
!something=does something else
!anothercommand=does another command


This does split the ini file up some, but it's a quick and easy thing to change. Note that it's not set up to do more than one $me response per command, unlike the random responses for the command when the nick isn't yours.
