I've figured out how to override them (the Wiki doesn't go over it), but amember.css is -still- loading it's goofy styles. Is there a way to simply disable all default css from being loaded or do I just have to delete the .css files from the default theme?
Figured it out. This is messy... I'm using WordPress and the plugin has inline styles that apply to everything. To fix it, I had to go into /amember/application/default/plugins/protect/wordpress/amember.php and delete all that junk. Note to developers: don't put styles in anything other than a fallback style.css
