Not quite my question - we are already on the unlimited plan. : ]
Let me see if I can clarify. Can we set it up so
Our Client A can be limited to 24 students or fewer
Our Client B can be limited to 140 students or fewer
And Client C can be unlimited
We would set the client's fee and configure the limits on our end - these are government-mandated training programs and our client incurs differing amouts of costs depending on the complexity of the required training. Other than these questions, your shrinkwrap LMS solution is perfect.
