Your username can only be changed within a 3 day window after registration.
New users can change their username within 3 days of registration at no charge. Even if changed within the 3 day window, old posts with mentions and quotes will have the wrong name embedded (which is why we limit the change period to only 3 days).
If your account is older than 3 days, and you don’t want to continue with your username, you may simply create a new account (at no charge) using a different email address. Content associated with your old username will not be associated with your new username. If you’d like, we can merge the two, but that involves a professional tech’s time. As of Aug 2018, the price for this is $50 payable by credit card. If you want this, write us at the address shown on our About page.
