Once you have created an account you can use your username and password to login. Getting your password has been fixed. Fingers crossed. Thank you for your patience on this matter.
After you have logged in you will see a couple of links in the lower left of this page. One will take you to the most basic of profiles. (username, first name, last name. etc) and you will be able to edit it. The username cannot be changed. Once you picked one that will be it. The system will not allow duplicate emails or usernames.
Then of course there is the universal “change password” link as well. Thanks for your support.
