UKFC, the group that helps us facilitate donations from the UK through their tax system, has a new website. We'll need someone in tech to review their new payment option for security standards.
url for their site: www.ukfundforcharities.org
I believe this is the url for their donate page: https://www.ukfundforcharities.org/donate/
