Hmm... I don't recall what my username is and possibly my password, and the site doesn't offer help if you don't. At least on that page.
Edit: I'm guessing I had to setup a new Neon account. Did that. Still not working.
Edit 2: checked my email, got this from the NSS "The rest of Neon is not yet active, so please DO NOT create or renew a membership or make a donation at this time."
