if you know how too that is... lose the ini files an use hash tables. that will save the wear and tear on your hard drives. also for the addition of the Master/assistant etc... use /auser , /guser etc. cleaner and simpler. other than that some flood protection wouldnt go amiss. a simple stopcheck would be sufficent as per my snippet on page http://www.hawkee.com/snippet/3874/ where i posted this code

on *:TEXT:<whatever in here>:#:{
  if ( %test. [ $+ [ $nick ] ] == $null ) {
    set %test. [ $+ [ $nick ] ] 1
    .msg $nick <message or action>
    .timer 1 10 unset %test. [ $+ [ $nick ] ]
  }
}

that there is a simple stop timer of 10secs for any single user trying to access the same command during that time.

other than that you have a nice code there and i am gonna give you a 4 for when you update to include some flood protection on the command access etc
