head over to her site. In the top left corner of the sidebar is a donation box.
I have admired Renee and her work for some time now. She's put a lot of effort into her site, and works daily to challenge racism, sexism, homophobia, transphobia, disableism, and many other forms of injustice. If you can help in any way, please visit her site.
My deepest condolences to Renee and her family during this time--losing a loved one is heartbreaking, and even more so when one is lost so young.
