TNG (or The Next Generation) is a specialist CMS for genealogical data. For more information on the product you can visit their site at tngsitebuilding.com. I have used TNG for many years and have found it to be a most excellent product that is incredibly well supported by the author, Darrin Lythgoes.
Being a form of CMS (Content Management System), it is designed to be hosted on the web (in the cloud!) and accessed (from anywhere) via any web browser. I have hosted my own TNG instance since 2005 and have the facilities and expertise to offer hosting of this product to others. Please contact me directly for more information on this, including setup costs and annual hosting charges.
