I should have mentioned that you must create a profile first, here: http://bugs.python.org/user
Your "username" should be included in the creation of your profile on the PSF bug tracker. So, if you need help with this, maybe Martin or one of the committers will help explain to you how this system works.
I hope that helped.

Thank-you for submitting your contributor agreement to the PSF. I would
to add your contributor form to the online bug tracker, however, you did not provide me with a username.
Therefore, I will not be able to access, view, update, or make any
to your online records until you provide me with you username.
Ah, OK. Did not see this on the form. I think it's best to use "sbrunthaler" as a username, unless there is another preferred naming schema.
