I figured out what was making the join us page not validate. I had left a couple of DIVs that were part of a code fragment of an attempt to make the "Default Button?" question on the Game Registration form stretch to fill its allotted space. Removing those old DIVs made it validate. Also, I've fixed all pages on the site so that they use the updated stylesheets include so that it doesn't display "PTv4 (preference)" for the stylesheet name whenever you pick a style, but instead the real name of the stylesheet, such as "PTv4 Blue". Additionally, I've added label tags to all the appropriate fields on public pages that have forms so that they're more accessible to the disabled.
