Till this day the newsletters for the freeware programs "HpglDxf", "RPNcalculator", "TreeMenu" and "UnitConverter" were offered additionally to this News-Feeds. From now on, the newsletters are dispensed.
Switching to the News-Feeds was inevitable, as each newsletter mailing caused significant afterwork and data security requests. I thank all the subscribers for their loyalty and understanding.
