Summary: DevOps Stack Exchange will begin the nomination stage for a special election on September 23 to bring in two more moderators.
For full details of the process, see the announcement on Meta Stack Exchange. The timeline:
On September 30, if there are three or more candidates, we'll run an election. If not, I'll simply appoint the candidates. (There's a small chance we'll need to remove a nomination, but I doubt that will come up.)
If there is an election, I'll announce the results on meta on October 8.
(Note for current moderators: there's no need to nominate yourself even though you'll likely get an email saying you should. The system assumes the first election is a graduation election, which would mean moderators would need to be re-elected. This isn't that sort of election.)
