My experience with CaringBridge is that it is extremely helpful, and can truly help parents/families when a child is ill, as the original poster suggested. I think it would be an excellent support, allowing friends of an ill child an efficient way to share information related to the child's health and condition with family and friends, but to receive information and messages of support in the guest book area in ways that are sensitive to the time demands of dealing with a significant illness.
Flickschool is a collection of ideas that have helped the San Fernando Education Technology Team (and its evolutions) throughout the years. We hope this site helps you produce the coolest projects.
Alot of information of various topics related to tech use can be found by checking out the various links, some of which have the actual presentations available (such as Digital Storytelling on a Shoestring).
