Thanks RusselB and everyone, you've all been a great help.

Okay, I have a second thing that I need help with. I would like it so that when a user types in !start, they get 100 points automatically. However, I only would like to have !start work on a user once.

For example:
<George> !start
<%[PN]Points> 100 points have been given to George
<George> !start
<%Points> Sorry, but you already earned your 100 points

Code:
on *:text:*!start*:#: {
  if ($1 == %c $+ !start) {
    .inc 
  }
}


I wasn't sure of what to add for the 3rd line. I didn't know if this would be an .inc command or not.
