M.P.
We used Caring Bridge, and Wordpress for my mother as she battled cancer and lost her fight. We made her Caring Bridge site public. Since she was a strong pillar in her community with many non-close friends and acquaintances it was easier to keep a daily blog on her struggle and tell people about the site, than explain it every single time we ran into concerned friends. As far as explanation it was a bit self explanatory and part learn as we went along. There are many sites that offer tips and advice on blogs, I just googled or Binged them.
All my positive and happy thoughts to you and Lilian. Strong, optimistic parents will help her along!
