Messies.com had a teleclass for Hoarders, Family & Friends on June 18, 2007.  Listen to it for free (for one week) below:

From their website:
Help for Hoarders, Families and Friends

Dr. Neziroglu also has a special desire to help family members learn how to help their loved one who hoards, to get them to at least the first step of help. She wants the family to know that there is hope and where to find it.  We had an informative and helpful conversation with Dr. Nez., the author of the very practical and insightful book, OVERCOMING COMPULSIVE HOARDING on our most recent teleclass on July 17th.
