E-Maintenance announcements
when there's one, normally a mod makes a thread about it, and usually the post includes some variation of "we'll update you as soon as possible".
when the maintenance is over, they respond with "The Contest is back up and running".
seems like when they say they'll update us, it only means letting us know when the maintenance finishes.
we don't get told what issue caused the maintenance, what got fixed during the maintenance.
i don't know about the rest of you, but when someone tells me they'll update me on a maintenance, i think they'll tell me what was the issue that required a maintenance and what was done to fix it, or long story short, what changed / what was done during the maintenance
