Code:
on *:connect:{ 
  //.timer 0 1800 msg #channel $!read(textfilename.txt,n) 
}

to read a random line froma txt every 30 minutes
Code:
on *:connect:{ 
  //.timer 0 1800 msg #channel <message i want to say> 
}

to just msg something you specify every 30 minutes
this is if your looking for a remote if u want the manual command im sure you can derive it from the above

The Kodokan will move you, one way or another.
