Hi doc,
Welcome to the board. I am glad you are making friends here already, I know I have made some very good ones. For each one of us, if and how we technically "leave" the borg is a very personal decision. Some choose to drift quietly away so as not to lose family members, some are forcibly pushed out and are very angry and bitter about it. Some cannot tolerate keeping the things they have learned quiet and feel honor bound to speak their mind. It doesn't matter to us what you do about that. We will offer you support and encouragement wherever you are on that road, because we have all taken one of those paths.
Good luck to you friend, and take care.
