Miss M, I may have many failings, but I don't think I'm stupid. I refer you to the MIA website, where visitors are invited to 'make a donation to Marple in Action towards campaign costs via registered charity Marple Civic Society'.
The point I was making, if I need to spell it out, is that the Civic Society, as a registered charity, has a number of tax and other financial privileges. That's fine, but if MIA (which is not a registered charity) is receiving donations channelled though the Civic Society, which have therefore benefited from those privileges (such as tax rebates under gift aid), then that may amount to misuse of its charitable status by the Civic Society. That's all.
