The Community Review Dashboard is finally nearing something we can call "release quality". All of the major categories from the old system are in place, and the time has come to address those stinkin' badges...
The old reviewer badge had a fairly complicated set of criteria (1000 reviews, over 200 actioned, predicated on first earning Strunk & White), and that's not something I'm interested in explaining (or even understanding) any longer. So we're replacing these with three new, per-queue badges:
Custodian is awarded for the very first review made in a queue.
Reviewer is awarded for 250 reviews in a queue. This replaces the badge of the same name awarded for participation in the old system.
Steward is awarded for 1,000 reviews in a queue.
Each of these badges can be earned once per queue - so currently you can earn up to five of each type. Badges earned under the old system will be retained, but can no longer be earned.
In recognition of the heroic effort put in thus far by the folks who've helped to test these systems and clear the backlog, we're awarding these retroactively. And because it was previously a separate system, we were able to preserve historical data on suggested edit reviews - so the folks who labored to keep suggested edits under control prior to the new system will be getting a nice pile of virtual precious metal.
We still have to implement a progress indicator showing your march from one badge to the next, but the criteria are simple enough that for the time being you can calculate it easily by viewing your current statistics in any queue.
