I am struggling with forum life. Can't figure out how to post pictures. This is very frustrating for me since I am an retired mechanical engineer who used to work at the Pentagon and contracts with NASA. I know that I will get it eventually. I am a smart person who feels so stupid not getting what most people find so easy. Now if you want to talk about how to deploy an antenna boom on a satellite in space, I am your girl. Posting and pictures in a forum is a mystery to me. HELP!!
