Possible bug: I cannot go back from the home page. Here is what I did. Visited the about page, then came back to home page and clicked on Register.

Now if I click on the back button, it's trying to send me to the portfolio, and since I don't have one now, it's redirecting me to the home page.

I have to hold the back button and select a page to go back to, which in this case was HN.
