A new SciCast ad campaign has created ~1,000 registrations per day for the past couple of days. That has doubled our forecaster community and created a lot of activity, which is great. But it also generated a lot of email notifications for users who had opted to receive updates for new comments, and more email is not always great.
After a dozen or so complaints and a review of some comments, we have disabled email notifications until we add some more controls.
