+The author's website, http://www.pootpoot.net, no longer exists as it once did,
+instead being something else entirely. The Internet Wayback Machine, although it
+archived it, did not load scripts. Do you know if the domain was moved? Do you
+have an archive or mirror? Please provide us it! Thank you.
