From the HNF email newsletter:

The Hereditary Neuropathy Foundation has recently made changes to its website. Informative areas such as the FAQs, newsflash articles, e-newsletter and the forum discussions will remain available as no-cost interactive features allowing individuals to communicate with one another world-wide. The section housing articles however is now offered as a membership feature accessible through a donation-based subscription registration at a minimum of $35.00 per year.
