As a complement to my update yesterday, the call for candidates to form the first Code of Conduct Committee has been sent to wikitech-l, mediawiki-l, engineering, labs-l, analytics, wiki-research-l, and design. It will be advertised in other technical spaces in the next hours. You can read it i.e. at https://lists.wikimedia.org/pipermail/wikitech-l/2017-March/087731.html
The next logical update here will be the presentation of a list of candidates to be reviewed by the Wikimedia technical community and anyone else willing to chime in. If you want to follow this process closely, you can check https://www.mediawiki.org/wiki/Talk:Code_of_Conduct#Bootstrapping_the_Code_o... or subscribe to the Phabricator task linked there.
