Ok. With that last post, I believe I've completely caught up with all outstanding private emails requests. If you sent me a private email via the contact link on this blog, and none of my recent posts answer it, then odds are a) the spam filters ate your email or b) I lost your email (sorry!).
 I also believe I've replied to all pertinent comments.  If there's an outstanding mail or comment; please re-comment on the appropriate blog post and I'll get to it. FWIW, Posting comments is better than sending me email because it's more public and so other people with the same question can get it answered.
