I went looking for the NAF site (bloodbowl.net)? I can find a cache from October 13th in Google, but any attempts to get to the site now goes to one of those annoying "We'll find this site for you" pages that finds nothing useful.
A friend was wanting to get a membership in order to get the Block Dice. At the moment, I may direct him to E-Bay. (He's not yet ready to order the box set from GW).
Any info would be appreciated.
