Quick update -- we now have more than 2,000 sign-ups. I figure that's a good base to work with (or if it isn't, there are bigger problems), so I've turned down the banner to about 20% and will disable it soon. Expect the frantic sign-up rate on MW.org to drop.
You may have seen first bits of code pop up here and there; we'll next send folks an email with some of the standard pointers, also in an effort to re-engage people who signed up a few days ago but instantly forgot about it. ;-) Greg's also going to send out a call for volunteers to help with the judging process.
