Nóirín was also a life-long volunteer Medic with St. John's ambulance in Ireland: http://www.stjohn.ie . I'm certain her family would appreciate any condolences or donations in her name.
I spoke with Nóirín's mother and brother this morning, and they know that she had a huge impact on people, and "on the web" (to use her proud mother's words), but I think it's worth making concrete. If you have a story or testimonial about how Nóirín helped or inspired you (and I know there are many), please send it on to colm@allcosts.net and I'll make sure to pass it on.
