This is your aforementioned Friday email:

I've pushed this back to Tuesday (28 March). The vague timeline is:

 * Monday, afternoon PDT: the Mercurial repo and Shepherd will become
read-only, and Mercurial will stop being sync'd with GitHub.

 * Tuesday afternoon BST: the merge will land on master on
web-platform-tests; all future pull requests and issues should be
filed on the web-platform-tests repository. csswg-test will become a
historical archive, and almost everyone with write access will lose
it. Hopefully (though not quite certainly) all issues on csswg-test
will be moved over on Tuesday afternoon as well (failing that,
Wednesday morning).

 * Wednesday/Thursday: all open PRs on csswg-test will be moved over.

PRs that would be a pain for me to move over are those with any
reviews/comments on actual commits (as opposed to the PR itself).


I would very much it appreciate it if those three PRs could get landed
before the Tuesday!

As a final reminder, a near-final merge is available at
(i.e., the csswg_test_merged branch on web-platform-tests). If anyone
has comments on that, please let me know!
