Researching username, password change problems 3 years ago

We’re currently researching reports from users who are locked out after trying to reset their passwords or change their email address or user names.  This seems to affect new users as well as long term users; we do not advise changing your user name, email address, or password at this time.  We will update Status with more news as it becomes available.

Update (Thursday 3:58pm):  We’re still working on this problem, and encourage you not to make changes to your email address, password, or user name during this time.
