Just search with the Site Search to the left with Mac. You'll find what is available here besides this thread. I updated the search engine catalog last night.
I thought of another possible reason to get a Mac after my post. You are a teacher and your school uses them. Another is fanaticism... Actually, many years ago I was an Apple enthusiast, quite negative on the IBM PC, and used some of the first Macs and a Lisa (if anyone can remember those). Of course that was back in the days when the user interface on an IBM-compatible was the DOS prompt. If Apple had played its cards right Jobs would be the richest man in the world. Perhaps they still could to a lesser degree, considering the fact that the latest Mac O/S is unix-based. If Xerox had played its cards right neither of them (Microsoft or Apple) would have had much of a chance. I am sure other Mac users would appreciate some input networking them (it they can get past my insults). Larry
