While I understand BeerPal's concerns, I believe that changing the rules to favor the traditional (stereotypical?) concept of a homebrew club would be a mistake and lead to rather arbitrary rules as to what constitutes a club and what doesn't. My club doesn't have officers, regular meetings, or dues. We are simply a group of friends who run into each other at the shop, bars, the occasional party, or beer tastings, and we feel that changing this would take the fun out of it for us. The same applies to the BN, except that it is national. Any change in rules will disadvantage any club, no matter the size, that doesn't fit the mold of the traditional club, not just the BN. Enforcement is another matter entirely - we are talking about the AHA here, which can't even ensure that round 1 of the nationals is run in a fair and effective manner in all regions (looking at you, NY!)
Should the BN defend its title, I am sure that the other clubs will respond by either focusing on the Gambrinus award or forming their own extra-regional alliances to even the playing field.
