I was just chatting with Martin, and a few things came out of it:

1. It would be good to ensure that the captcha field is visually different (it's possible that some people won't read the label but will simply type their password in there...being so used to entering their email followed by a password to create accounts etc.)
2. It might be good to have some indication of why we're asking for a maths question (as above) - but it doesn't need to be prominent.

So along those lines, here's two thoughts - see what you think:

1. http://people.canonical.com/~michaeln/tmp/captcha_eg1.png
This deals with (1) by giving the field a normal label and moving the question into the right-hand column (similar to what gmail does with their 'Word verification' when you try to register an account). That said, I don't particularly like the smaller input all on its own... so,

2. http://people.canonical.com/~michaeln/tmp/captcha_eg2.png
shows another idea - modifying the question to simply 8 + 8 = and having the input inline there. This looks much simpler to me and is very hard to mistake as a password field ;). I'll see what you guys think.

Note, in the second screenshot, you'll see that I also added the explanation of the random question to the steps above the fields - this seems like a good place to put it (as it is a required step) and it keeps the form clean. Another thought Martin had was to have a small '?' help link next to the question that would pop-up an explanation.

Anyway, let me know what you think.
