Hi Tom,
Thanks. And yes, you are right that having active users providing feedback is the key. I remember when I first created AI 1.0, I looked at your site and tried to incorporate all of the modifications you had made (as well as some of those from Jack Park).
When I had done that I thought, well that's about it. I'm not sure what else I can put in there. Then I released AI 1.0 and received a flood of suggestions that I hadn't thought about. Many have made their way into subsequent versions of AI and thus made AI a far better product than I could ever have created on my own.
Don Carlson has been instrumental in not only providing enhancement suggestions but also in testing and discovering bugs and such. Of course there have been many others too (AIMster for one) over the years.
But looking back, it all started with Lichello's book and then your Website.
