Two months after converting my first Chess Tutorial, on a positional principle titled Maximize the Usefulness of Your Moves, I completed a second, Opening Tutorial : Sicilian Defense - 2...e6 Variations. The total time to convert it was about two hours.
I have 13 more opening tutorials plus another 20 tutorials on other subjects. I picked the Sicilian 2...e6 subject because I'm adding the line to my repertoire and wanted to see how useful it is. Since I'm no longer bound About.com constraints on article size, it can definitely be improved.
