To answer Lodewijk's question it is all the Wikimedia projects, and not WMUK's activities, that we need to show public benefit from (without saying too much, anyone who finds this puzzling might start here).  There is also a special page set up on the WMUK website at http://uk.wikimedia.org/wiki/Charity_status_application/help_wanted for responses, or they can be emailed to me.

Thanks,
John (Johnbod)
