One easy way is to submit another application, and in the text field, say that you are updating your information. Alternatively, you can send an email to betatest@ldw.com with any updated information, but (of course) we don't accept new applications by any other means than the official beta test application. In either case, make sure that you include your forum name, so that it's easier to make sure I'm updating the right person! I do know all of the regulars here on the forums, but I don't memorize email addresses.
