First - a big picture in plain words of exactly why WIX has nailed the ultimate website builder editor without resort to add-ins (and the money pit they lead to!)
Second - a master index of topics covered in these amazingly helpful articles.
Third - A road map of an intelligent path for a newbie to the WIX database features to follow, interleaved with links to the Tutorial Videos as they pertain to any given article.
Thanks,
