Basically we are replacing an existing system with a much cleaner and faster VFP9 application with a SQL backend. Sales application. I've decided that there seems to be different levels of users skills and I've sorted it into 3 rounds of training with 5 people in each group. So 10 trainng sessions a round, 30 presentations and trainings, exciting.

Thanks for everyones help, it gave me a good idea of how to approach it.
