I had come across an article on theory and implementation of hooks for plugins awhile back (linked from slashdot, I believe), and I thought I had bookmarked it for later reading. Well, now I can't find it. So I'm asking: does anyone know of any resources online that covers this sort of thing? I'm not ready to begin implementing such a thing. I just want to learn how it's done and get a good overall feel for it. Thanks. yckx
