Esther, why don't they want to brainstorm with you? With your access to many clients using MAS in many different ways, I would think you would be the go to person for best of breed ideas. Many times, the optimal solution is to use MAS more AND to change their internal processes to take advantage of MAS (and Excel/Access/etc). Yes, talking wtih other users is helpful to break the inertia and that is where the Summit might also work to your advantage.
