Summary: Korean Language Stack Exchange will begin the nomination stage for a special election on September 24 to bring in one more moderator.
For full details of the process, see the announcement on Meta Stack Exchange. The timeline:
On October 1, if there are two or more candidates, we'll run an election. If not, I'll simply appoint the candidate. (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 9.
(Note for current moderators: there's no need to nominate yourself even though you'll likely get an email saying you should.)
If you have any questions about the process, please stick them in an answer here.
