Just joined and don't see anything here yet so I thought I'd toss this out to get started. My name is David Staudacher. I manage the "Mainframe (COBOL, etc) Experts" group and co-manage the "Mainframe Assembler Professionals" group on LinkedIn. I mainly use the efglobe/Dezhi Mainframe to test sample code before posting it there. I love it! I'd also love to know more about it and the people who keep it up and running. It's clearly a labor of love and a precious resource to those of us out here who sometimes need it.
