Content changes on What's Changing page

I've made some content changes to the What's Changing page text to talk about the Charities Open Access Fund: https://docs.google.com/document/d/1JUrrgzG0zN6NEp6fjcQLcUuGtazos5Uhl2EjiKUJdIc/edit?usp=sharing

I suggest replacing all the text as there are several small changes.
I think this needs a comma between `accepted` and `upload it`
