on ^*:open:?:{ 
  if %stop == A && !$hget(fdlist,$nick) { 
    if !$eval($+(%,query.,$site),2) {
      .msg $nick Hallo $nick ask to talk to me in a channel. I'm not accepting private massages from you
 
      ; this var simply limits your auto-message to the same user to once every 15 seconds
      inc -u15 %query. $+ %site
    }
    halt
  }
}
