Hey trikola, you should put all those On Text events into one large on text event like:

On *:text:*:#:{
  if (!%poll) {
    if ($1 == !Trigger1) { action 1 }
    if ($1 == !Trigger2) { action 2 }
    if ($1 == !Trigger3) { action 3 }
  }
  else { msg # There isn't a poll right now, make one with !makepoll }
}

Also, you should consider using while loops over goto loops and also you can unset more than one item on a line and lastly you should try to leave out the halts when the 'if then else' already handles the halting by not doing anything and ending the routine:

alias end.poll {
  var %number = 0 
  while (%number <= %options) {
    inc %number 
    msg %chal  $+ %number $+ . %option [ $+ [ [ [ %number ] ] ] ] -- %vote [ $+ [ %number ] ]
    if (%number == %options) { msg %chal there was $iif(%votess, [ [ %votess ] ], 0) vote(s) }
  }
  unset %poll* %vote* %option* %pmaker %polltime %ptopic %num* %chal %wrote*
}

Instead of:

alias end.poll {
  :again
  inc %number
  msg %chal  $+ %number $+ . %option [ $+ [ [ [ %number ] ] ] ] -- %vote [ $+ [ %number ] ]
  if (%number == %options) {
    msg %chal there was $iif(%votess, [ [ %votess ] ], 0) vote(s)
    unset %poll*
    unset %vote*
    unset %option*
    unset %pmaker
    unset %polltime
    unset %ptopic
    unset %num*
    unset %chal
    unset %wrote*
    halt
  }
  else { goto again }
}

I havent tested this yes but it looks decent.
Maybe ill give it a shot when you try those changes, especially combining all those on texts.
