The wiki for Doug Belshaw’s book appears to have an issue preventing new users from registering, making it impossible to post reflections on chapters 1-5 of Essential Elements. I’ve inquired with Doug and hope to have some kind of resolution ASAP.
Until then, if you are reading those chapters and unable to reflect there, you can do so on your own site/blog. Worst case: that will be the new normal. Best case: Doug fixes the wiki and you can just post a link or copy/paste as needed. Until then, don’t let the wiki issue slow you down!
