Some of the posts/articles here are unedited first drafts. I have found that it's more important (for me) to just get the words out and clean up the errors later. Slowly I am beginning to edit what I've written and present the material in a more polished form. Some day, I hope to publish much of this material in print (rather than virtual). Of course, the way the planets have been spinning around lately, that may have become an impossible dream?
