@Alexander Rohmann on this.

I'm looking to theme my wp-signup.php page. I've tried this plugin: http://wpmututorials.com/plugins/style-your-signup-page/

It helps a little, but the page is still not inheriting my entire header or footer of my theme.

I've heard something about page-signup.php and adding it to my themes folder.

What could you tell me about this?
