Charitable status is a difficult thing to work through. If its made so difficult for say a church, synagogue or mosque, its much more difficult for an organisation that appears to only have a cyber presence.
Chapter v supporter group? Is that not making even more complications in tying up the loose ends of charitable status. Does it also allow chapterists to make changes to the constitution (like often happens in synagogues and mosques?) Whats to stop wiki-haters filling up the chapter with their supports to force constitutional changes etc. As a limited company, the board it protected from outside attack.
