Online Scheduling

Our flight school is currently trying to move to an online, internet
based scheduling system, using a service provided by "MyFBO".

The idea is to schedule via the internet (even when standing at the
counter at the flight school) for all flights that occur after the
current day. Every morning, the staff will print out a schedule for
the day and any changes for that day must be done to the paper
schedule.

The consensus of the flight instructors and staff is that the
interface is extremely difficult to use, and slow. There will be only
one computer available for all users to make changes to the schedule
and the internet connection is a bit flakey. While frequent users
will probably be able to learn the system, it seems unlikely that
students/renters will develop any kind of proficiency with the system.
As far as I can tell, there are no contingency plans about what to do
when the system goes down.

Does anyone have an experience with online scheduling with large
flight schools? How well did it work?

Thanks for any thoughts.
