OSARCC are a fantastic collective of "women committed to supporting survivors of sexual abuse, rape, domestic abuse, and harassment". I helped them to get their website transitioned away from flat html to a simple CMS, Sky Blue Canvas.
Their main requirement was that whatever system they ended up with should be super easy to use. In addition they needed a CMS that didn't require a database backend. Sky Blue seemed like a decent fit.
One of the members of the collective has now taken over as the web support person and has since redesigned the site with OSARCC's new logo and colours.
If you have some spare money, I’d really encourage you to donate on their justgiving page. They really are an inspiring group.
