Well GitHub definitely works with ProIV 8.3. The one thing we didn't like about GitHub was that we couldn't tell who made the changes. Maybe there is a way but we missed it in the demo. As a group we have decided to see what else is out there before we commit to a solution. If we go with GitHub we will get Andrew Turner involved in the setup as he already had it setup for the demo. I will keep you posted as to what we choose.
