Summary: Medical Sciences Stack Exchange will begin the nomination stage for a special election on October 22 to bring in one more moderator.
For full details of the process, see the announcement on Meta Stack Exchange. The timeline:
During the nomination period, users may nominate themselves and answer any questions that might have been asked on meta.
On October 29, 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 November 6.
(Note for current moderators: there's no need to nominate yourself even though you'll likely get an email saying you should.)
Medical professionals preferred
This isn't something we normally concern ourselves with, but given the nature of this site, medical professionals are encouraged to run if interested. We won't be checking your licence, obviously, but it would really help evaluate answers and effectively moderate the site.
If you have any questions about the process, please stick them in an answer here.
