Now the interesting thing would be "did" he block just the forums URL or the IP address.
Maybe (and Kai could pass this on) if he tried accessing the forums by either
http://www.oddworld.au.com/forums or
http://216.101.14.114/forums he might be able to get in.
Of course this is all dependant on what was blocked. If he blocked the IP it won't work... but it's worth a try. Good luck!
