@Bob_Catly, there is a thread with instructions for people with a previous username to get the new account merged with the old one so you can retain your posting history. (Your old name is still here, but it was changed to Hi_Medlo. Now you have 2 accounts.) EngineerCompGeek will fix you up.

Send me an email at EngineerCompGeek@gmail.com and we’ll get you sorted out.
