K. Peachey - Perfect! That's exactly what I was looking for.
Jidanni - No worries, I know we can't force them to read it, it's a legal thing.
Platonides - Thanks for your very thorough answer! I didn't want to modify the template because I was afraid it would get lost when we upgrade. I really appreciate you showing how to put the extension together though; I haven't quite gotten to the point where I'm writing these myself rather than downloading them, but I found your code very helpful in understanding how extensions connect with the hooks.
