In June, we had a Moderator Election here at Stack Overflow (as well as on other sites, which we'd continue to run several over the course of the summer). While the running of the election wasn't distinct from any past election, what was different was the form of notification we used. Instead of a System Message, we opted to use the brand new Community Bulletin. But this wasn't fully satisfactory. While part of the intent is that people who are not interested in the governance can skip over it, it is a major issue when the people who are interested are not properly notified of these events.
While a lot of the discussion on this originates from elections, the Community Bulletin as a whole could use some improvement. Part of the reason we introduced the bulletin was as a means to allow the community and its moderators to easier promote elements like contests or important meta discussions - things which we forbid moderators from using System Messages for. That way, the System Message remains a utility for identifying critical server notices and outages, but the important-yet-not-dire stuff is still visible.
We're considering reinstating the functionality of System Messages to hold election notifications, and also at the same time making it dismissable in some fashion. System Messages will now be restricted to solely system critical announcements and for elections. Thoughts?
