Some users were running into difficulty getting a new password emailed to them post redesign. It appears we may have dialed security a bit too tightly and user accounts were getting locked out after only a few failed login attempts. We've relaxed things a bit, so hopefully this will no longer be an issue.
This seems like a good time to mention again that the security of your data is taken very seriously around here. We try to err on the side of too much rather than too little.
