when making comments, put a ; at the beginning of the line

-----------Join Notify All rooms----------------------------------

on *:JOIN:#: { msg $chan $nick has joined our convo }

umm thats would only notify one room, try

on *:join:#:{
  var %x = 1
  while $comchan($nick,%x) {
    msg $v1 $nick has joined our conversation
    inc %x
  }
}

:P
