Charlene left behind many things, one of which was a blog that she managed. It predates the website and was here that she garnered support and built a following. Beginning in 2009 up until just a few days before she died, it contains some insights into her health and a sense of the excitement she felt at various stages of the fundraising journey.
You can find the blog here: http://charlenesproject-theschool.blogspot.co.uk
She also was the original designer of the first website to feature the project. You can see it here
Please note the design is old and some of the links no longer work.
