Not only are there many discussions in the main Forum but most of the 69 groups have Discussion Forums of their own. Since you are trying to get information on Donald Hanks I would call your attention to the Thurston Brooks Merchants Association group which Don Hanks and John DeMott had set up. They set up the Don Hanks account on Location19 using the email@example.com email address which they both could access. John DeMott is the person you want to contact for information on Don. You can probably reach him by emailing firstname.lastname@example.org.
