First off, I am quite pleased to see that Stack Exchange is now an OpenID provider. I see this as a very good thing for not only Stack Exchange but also the sites that will now be inspired to add OpenID support.
I decided to give it a spin, so I went here:
Unfortunately, I couldn't help but notice that there were no labels next to the form (which is certainly recommended). Although clear to me, some people may have trouble figuring out what "John Smith" means. (Indeed, I thought it was tradition to use "John Doe" in place of an actual name.)
Would it be possible to put form labels next to the input elements?
