I found the name "mirazjordan" as the creator and editor of some Wiki pages in 2015. As a Forum user, they joined June 30, 2015 and made their last post July 6, 2015; they were active for one week. The Stairways Software blog mentions "2015 also saw a massive improvement to the wiki".
My guess is that @peternlewis hired Miraz to help with catching up the wiki to the new features of the product. The pages by them that I've seen so far have been pretty perfunctory outlines, placeholders rather than guidance.
My hunch is that any pages by Miraz would be good candidates for an update review. I've already updated the page on "iTunes Controls" to say "Music Controls".
Docuwiki has a couple of extensions available, Authorlist and PageQuery, which may allow searching for pages by a specific author. I imagine PageQuery would allow searching by modification date.
Is that of interest to anyone else?
