Always a disclaimer
To put it simply, either a topic has evolved or I have changed. In either case my relationship with the topic is not what it used to be. I have been reluctant to post anything largely because I find that as time passes may take on the topic changes as well. I hope to stick to generalities and only point out specifics if it helps explain the process. Oh, I'm not one to copy edit until there are no flaws; if you see an error, let me know. I will fix the page as needed.
