Well, I can say that the code works. However, this is one of the most horribly written scripts I have ever seen. If you want something to just stick onto your website then this is fine, but if you want to change anything, good luck, this guy's programming style is atrocious. I can't say I've bothered to look through his nightmarishly long script files, but his php code in the main html file is just absolutely unreadable and most of it is way more complicated than it has to be.
