I am a new member of the Indiana Genealogical Society (IGS). I joined IGS at the Federation of Genealogical Societies 2011 Conference, in Springfield, Illinois and have spent the last month exploring the online databases available to members. (I have Graf and Mast ancestors from Indiana. They were primarily in Howard and Miami counties in Indiana.)
Many of you have probably heard of the society's recent success with raising funds for the War of 1812 digitization project. Currently, they are working on a probate preservation project for Hendricks County, Indiana. Other projects IGS is involved in are listed on their website.
IGS has a Facebook and blog presence. Both are very well done. I encourage you to take a look at the Indiana Genealogical Society. Check out their website, blog and Facebook page to see all the wonderful work they are doing with preserving Indiana genealogical records.
