Excellent, thanks for the link to the site. Looks good, and it's always nice to see where my work is used.
It isn't beta anymore, as I fixed all the things that irritated me (except it would be nice if I could find a way to add a parameter to the articles to exclude the footer, maybe in future!).
The only other thing that occurred to me might be useful would be if I were to extend the plugin slightly to allow a header as well - as far as I can see there isn't a plugin that does this.
Funnily enough, I was using Rereplacer before writing this plugin. It is the only other way I could find of doing a similar thing, but it just wasn't quite what I was after (even though it is an excellent plugin itself).
