There are 45 or so of these pages. Reading through some of them was one of the most useful ways to learn vim.
What's weird is very few blogs or articles mention these even existing despite the suggestions for using vimtutor or reviewing the :h command for finding help on specific settings.
Perhaps this is because both vimtutor and the Emacs tutor do refer to their respective help systems, but given the sad state of most help systems beginners are familiar with I think they can be forgiven for not taking the recomendation seriously. Its worth really emphasizing to beginners that there is a follow up to the simple vimtutor/TUTORIAL built right into the editor.
