The VOLANT Charitable Trust
J K Rowling's site has an update, to include a link to her own Charity, based in Edinburgh.
The Charity furthers some of the long term projects JK Rowling is actively involved with by directing funds accordingly:
Research into the causes, treatment and possible cures of Multiple Sclerosis.
Charities and projects, whether national or community-based, at home or abroad, that alleviate social deprivation, with a particular emphasis on women’s and children’s issues.
