Most have no idea the kind of software you are about to show them. Acceptance of computers in C.E. is on their mind. Many will face some opposition in their congregations. A few personal stories will help. This is a teacher's medium.

Without good advice, many churches will load up on old equipment before they even survey what kind of software is available.

There are a variety of ways to incorporate computers into C.E. and there are a variety of software types. Early low-key experimentation will allow teachers to find their way.
