This is an interesting little problem. If it's what I think it is, it has nothing to do with events, per se. (Well, it kind of does, because you're attaching a method to an event, but the fundamental problem isn't tied to the event itself.)
I think the problem is that you're probably in the static Main method, trying to attach a non-static HandlePointChanged method to the event. The problem you're running into is the same problem that would prevent you from directly calling the non-static HandlePointChanged method from Main. You need an instance of the method to call an instance (a.k.a. "non-static") method.
In this case, one solution might be to make your HandlePointChanged method be static as well.
Your other choice is, of course, to leave the method non-static and create an instance of whatever class it's in to do the attaching. From the Main method, this means creating a new instance of the default Program class (i.e., new Program().HandlePointChanged) but in this particular case, it sounds kind of dumb to create an instance of the Program class like this.
Hmm… this last paragraph is a little on the confusing side. The point is, you can attach it to instance methods, you just need an instance of the type to attach things. Making instances of the Program class seems kind of silly here, but you may have other types that it makes sense for.
Considering the wording that is in the tutorial right now, I can see why this might be causing some problems. I should probably go clean that part up a little bit.
