Here is a list of the blogs I've been following about GRIP:
Catherine Desmarais blog: Stone House Historical Research
Chris Staats: Staats Genealogical Services
Becky Wiseman: Kinexxions
Shelley Bishop: A Sense of Family
Of course these are just a few blogs I've been keeping up with. I'm sure there are others that I'm not aware of. GRIP has also released the schedule for next year. The line up is very tempting.
