For 19 years now, there have been (and still are) 2 different Mozilla wikis now, written by the user community (http://kb.mozillazine.org/, still lacking HTTPS btw(!), and https://wiki.mozilla.org, the official wiki). It would be highly useful to start merging the two, by posting a visible notification on the mozillazine wiki regarding that, and asking users to copy the articles, that are not yet on wiki.mozilla.org, over there, and mark the original mozillazine articles as "move completed" or so. Once all is completed, kb.mozillazine.org ideally would be set-up to redirect to wiki.mozilla.org with a simple HTTP redirect.
(the most noticable difference I guess is that wiki.mozilla.org account creation might take longer than on the mozillazine wiki, as from my memory someone manually had to approve wiki.mozilla.org account registration. Not sure if that still is the case, is it?)
