Regular New York History reader and GeneaBloggers.com founder Thomas MacEntee wrote me recently to let me know about a wiki called Helderberg Hill Towns, and devoted to the the Hill Towns of Albany County.
Local native Hal Miller created the concept and arranged for volunteers to provide content to the site- the software installation and other technical components of the project were handled by MacEntee.
The site has 2,548 articles so far and growing, including architecture, biographies, businesses, cemeteries, documents, events, images, maps. military history, natural history, and a lot more.
