Delay for overnight May 8-9

We've discovered a technical issue today (May 8) that really, really, really needs to be fixed before we start mailing again. We're working on it, but I currently don't expect it to be fixed until early tomorrow. We'll get the mailings caught up just as soon as we can once we have the problem sorted out. Meanwhile, all other aspects of the service, including signups and unsubscribes, are continuing normally.

Update: 11:32 edt - we (ok, the comoputers) are working on the last phase of the changes. This requires database changes that will take some time to run - the site will not be taken down for this. ETA for completion is early this afternoon, US eastern.

Update: 16:45 edt - messages atre being delivered.
