Hello,
For easy reference (and for your information) - the "back end"
ruby quiz pages in the github repo now also get published (rendered)
on the "front end" thanks to jekyll (and github pages).
See https://planetruby.github.io/quiz for "easy-to-read" pages using
the default primer theme.
Cheers. Prost.
PS: All quizzes are still open - send in your code snippets 
or
questions and comments for public dicussions.
