Bob, congratulations on your retirement. Your commitment to your customer is exceptional. ACP software has been a great help in my astronomy. Nothing else compares. I wish Stephany and you the best in your retirement.
While support for your customers will end next year, there is lots of great help in the forum. I hope you would think about how to leave it all to be accessible to all users beyond that date. Also, it here is a your person that I would would be willing to setup an channel on Groups IO or some other forum where users could continue to help each other. This will be a great service to your faithful users who will want to continue using your software for years to come. Let your legacy continue.
Regards, Dick
