Honestly the TreasuryDirect website has always been clunky. If you forget and use the back and forward buttons it will crash, but also If you take too long asking a question in their email form, they kick you out of the system. I was fine with dealing with all of that annoyance, but they out did themselves with Requiring you to submit a form to them via mail if you would like to change or add a bank to your Treasury account. NOT ONLY that but also have a bank official verify your identity and have them stamp their medallion signature. All this to 'protect from fraud'. That is of course total BS. You have to mail a form with all your bank acct information and your SSN and pray the post office doesnt loose that. There you have it, TreasuryDirect protecting you from fraud by exposing you to identity theft.
