If you are seeing this page, you are seeing the server where the AppleCentral forums WERE. The forums were moved at 8:30pm pacific on 05-27-10. If you are still seeing this page, it's likely because your DNS is caching longer than it should.
If you know how to clear your cache, go for it. Otherwise, you may want to talk to your internet provider.
Or, you can wait for a bit, and it will likely clear up itself.
Is what I got attempting to come in through the front gate - http://forums.mactech.com/
even after clearing the caches in FF, Safari & Camino.

Very snappy on both SL & Tiger. Thank you.
