When I bought AC late last year, I also did not understand this credit card policy. However, at that time, there was also an offer to pre-pay for 2 years of support before the price increase. With Jon B's help, I was able to do that. I think it is much simpler and clearer to make such an offer to existing users before a price increase, rather than to track the credit cards. This allows AC to generate a cash infusion if needed for development, and gives each user a choice about the renewal price in a clear way. Although there are certain things that are a bit "rough around the edges" with AC, I appreciate the fact the Jon B. is so involved, and responsive and fair to users. When I was shopping for an EMR, I found no other company that operated this way. I hope we do not wear him out. We all have a vested interest in the success of AC.
