Status update (6/1): We removed blanket edit access for external news a bit over a week ago and haven't received any complaints, which I presume means there have been no problems. So we're doing news today. What this means is that you will only be able to edit news items belonging to groups of which you are a member. Please let us know if you see any problems stemming from this.
Status update (4/12): The system has been stable for a couple of weeks, though we're continuing to pare down the Mercury issue queue. If you have issues you want to see addressed, this is place to go. You can follow issues and see when we have updates or solutions. If you have an issue that is not already the queue, you can add it directly there or email email@example.com. If you have had problems regarding event times, disappearing keywords and/or categories, or problems with data feeding to your site, check our quick fixes to common problems page.
