As I said, it's a site with downloads for hundreds of free agent characters. Most of the time you will get the busy server error message, because, well, most of the time the server is busy. If you keep your patience till you get in, there are hundreds of free downloads, including several robot or android characters. They're only listed by name, so go somewhere like here
http://home.earthlink.net/~cook7777/ to window shop while you're waiting get into Bob Norris' site. (Clue: if Bob's site is busy, wait a couple of minutes and try again. Don't just hit refresh over and over, that just makes it worse.)
By the way, if you installed Cyberbuddy, it's worthwhile to go to the Cyberbuddy chatroom and meet Cyber the Bot, one of the best ai on the net. You may want to go to
http://cyberthebot.com/ to get his character and read up on how to chat with him.
More about downloads.
http://www.agentry.net/ has quite a few, though the site is not as good as when it was run by Microsoft.
