These are great, Tim. Thanks.
Unfortunately, I don't really have time these days to provide detailed corrections to these. What I'll do from now on is to take the notes that you send out, and edit them, and put them directly on the group page. You can see where you made mistakes (usually) if you just compare your original with what I put up.
I very much encourage you to do this, as I really believe that understanding your mistakes can help you to improve much faster.
Cheers!
