If you get a standard vbulletin favicon instead of the fancy little golden platypus, it is because your browser have cached it.
What you can do is go to http://forum.paradoxplaza.com/forum/favicon.ico and update that cache. So that is ctrl + f5 in firefox/ie and ctrl + R in chrome. Opera seems to manage it on its own.
