New forum registration anti-spam, new members please give feedback?

I've had to incorporate some new anti-spam as I was getting a spam registration about every 6 hours. This includes some questions to the user which you'll need a little Subaru knowledge to answer. The problem is, if you get them wrong the next screen after registration is just blank then when you go back and try again it says that email address is in use. All you need to do is go back to the front page of the forum and click register again, then your email address will work again.

Anywho, what I want to know from those who have registered with this new setup (and even those who had trouble and couldn't please email me) is was it easy enough? I'm getting no spam now so it is working. But I'm also getting about half the new real people a week as I did before. At lease this forum is still free, unlike ausubaru who charge for new members now.
