I believe that I over-comma my writing. I was going to seek your advice on comma'ing but then decided to Google it instead. I found this great site: Grammar Book with a whole list of rules about commas (in fact too many rules to remember). I tend to use rules 8 and 11 quite a bit. Maybe too much.
I'm probably still no further ahead. Next, apostrophe's, but for now: to comma or not to comma . . .
