My understanding is that the manager is now also inside MODx, so that it can all be modified and managed just like the rest of the resources.
They've added some of that functionality to Evolution with Manager Manager, which I haven't had time to play with either.
I haven't looked at Revolution at all due to time constraints, but I think I need to do so.
Sigh. Add item #3802 to the list of things to be done before Friday.
