I'm more of a CSS/XHTML guru, but I would love to help where I can. I've done a bit of ASP/SQL and would love to start learning PHP.
I also have a thing about web standards and accessibility so I might be good for helping out making the site valid xHTML1.0.
Ideally I'd like to make a new site a complete CSS layout, but seeing as none of the Amiga browsers support this yet, perhaps a basic table layout for older/amiga browsers, all styled up with CSS to make it look nice in a modern browser :-)
