Quick note before I go to sleep: with bundled efforts from Casey, Chad, Sam and me, we now have a mailing list that all CodeReview comments are sent to: mediawiki-codereview@lists.wikimedia.org [1], requested in bug 22046 [2]. Nice as another stalk list or if you miss knowing what's going on from the old days when commenting on code meant replying to mediawiki-cvs e-mails on wikitech-l.
The list is set up so only CodeReview itself can post to it. Replies are set to go to wikitech-l, but of course you should use CR's own commenting mechanism to reply to a comment instead. Just like mediawiki-cvs, this list is not archived. Tim and I are the current list admins.
