As many of you likely already know, moderators across the SE network have been engaged in a work stoppage since early June, for a number of reasons, which are outlined in the main meta post Moderation Strike: Stack Overflow, Inc. cannot consistently ignore, mistreat, and malign its volunteers. Nearly all of the Math SE moderators signed the strike letter, and have been abstaining from moderation for the last two months.
As of Wednesday, Moderation strike: Results of negotiations, negotiations between StackExchange and the moderators' elected representatives have concluded. Further discussion can be found at Moderation strike: Conclusion and the way forward. Because moderators on the SE network are a loose collection of individuals, the choice to return to moderation duty is up to each individual.
After discussion, the Mathematics SE moderation team has determined that the negotiated settlement is acceptable enough, and that we will be returning to actively moderating the site. Please be patient as we work to catch up with the backlog of flags.
