On the main site, the community moderator banner has disappeared. I can still see it on the meta site and access the election..but is it taken down or just my PC glitching up?
All banners are limited to 48 hours except during the "birth" of a new site. This is by design.
The featured meta election topic is the permalink on the main site.
(oh, and meta posts can only be featured for 30 days, after which the featured tag is stripped automatically to prevent staleness.)
It looks like system messages can only stay up for 2 days. I re-added it for now, but I suspect that it's a bug.
