It's likely to be taken down soon but as of 10pm on Tuesday 18th November 2008 it's available at http://bnpmemberslist.blogspot.com.
Most of the entries are just name, address, phone number, and possibly email address. But then there are those that describe hobbies and interests, and sometimes those interests are a tad bizarre.
Here's an, anonymised, example of hobbies and interests:
Tour guide ([XXXX] Cathedral). Writer for local paper (church/village history). Runs a Christian singing group. Vegan/supporter of organic produce. Members of the Woodland Trust, National Trust, VIVAI, Anglican Society, Open Doors, British Israel World Federation.Being curiouser than Alice, I looked up the British Israel World Federation. I thought it was a Victorian relic of Empire that had long since passed the way of the Primrose League and the Economic League. How wrong could I be. It even has a website.
oh, and being an activist in the fascist B*N*P.
Apparently they believe that some (go on and guess what sort of people they believe this applies to) people in Britain are descendents of the lost tribe of Israel and the country is thereby blessed by the spaghetti monster (or G_d or sky bully or non-existent entity).
I bet this fascist read the Da Vinci Code.
