Started slow, but I am refresh-reading various grammatical rules, most of which I already know. Thing is, this isn't a beginner's course, it is for those who should know better. There wasn't a level below that was a refresher hey-you-can-do-it course. A lot of handy hints have gone into a Quick Folder on my toolbar. Need to do some quizzes this afternoon before I plunge into the abyss.
