Glorianny
I don't see why anyone would try to close it down. It is another service in an area which has been sadly under funded like so much else under a Tory government. It's JKR's money and she's putting it to good use. I'm not happy that we seem to be heading back to Victorian times when individual philanthropists had to support services but that's another subject.
Well Mermaids have done their best to get charity status withdrawn from the LGB alliance, which would effectively shut it down. Were you unaware? That is exactly why J K Rowling has decided to fund this exclusively herself, so as to avoid similar treatment.
