Andrew, There is already some sort of e-mail notification capability built into the Wiki, although there seems to be some question over its usefulness on the UseMod wiki site. But that at least provides us with a starting point.
I've downloaded the source code, and will have a look see next week. There appears to be some sort of database format, so perhaps I can add a field to the page record as a quick hack. I'm not much of a Perl coder, so if anyone IS a serious Perl coder, I'll bet that they could hack it in posthaste. --- Noel
