I think there may be a few roles actually. As we transform the 'training department' into a 'connecting & communicating' hub, the former LMS Administrator(s) may in fact become Community Managers, but others within the org (like a sage on the stage trainer) may become a 'Connection Coach', or a 'Collaboration Consultant', or a 'Community Captain', etc.

We need to rethink all roles, not just the Community Manager. (although I know you are not stating this Harold - just furthering the transition notion)
