Each week – well nearly every week – we send an email to all HCA users and those who added themselves to our list. Sometimes we discuss recent technical support questions, and the answers are often of interest to everyone. Other times an interesting HCA application or HCA visual programs is looked at. And sometimes you get treated to thoughts on automation, programming concepts, or the future direction of HCA. It’s never junk or just an advertisement for HCA, and often entertaining. Below are some recent messages that might be of interest.
