I don't really recall receiving any sort of notification about this. . . . But anyway, I am indeed aware of XSS vulnerabilities in the software. My time has been devoted to overhauling my blog software, however. I hope to seriously rewrite the guestbook script as soon as possible. It _is_ a beta version. That may not be an excuse, but it should at least be a warning. Assuredly I'll make sure to get rid of the XSS vulnerabilities when I rewrite the script pending a final release.
