Internet Riddle

This is a interesting internet based riddle for geeks who have time to kill:

Go to http://n.nfshost.com/

The object of the riddle is to try to figure out how to get to the next page in the sequence.

For example, you start on page 1. Clicking on the 1 brings you to page 2. But there is no links to page 3! So you need to manually go to http://n.nfshost.com/3.html. But now you are on page III, so guess what, you need to go to page http://n.nfshost.com/IV.html. And so on and so on until you run out of intelligence.

There is actually a last page you can get to, but as you increase through the pages the difficulty to getting to the next page increases.

No fair using a google hack to cheat on this.
