please do not remove theme credit. it is there for a reason, plus i made it faint so it isn't that noticable. i have put effort into making these themes and kindly posted it for you guys to use. crediting me in your faq/about page is acceptable. thank you for being decent.
to avoid confusion, when "install and preview" is shown please click on the theme name again to exit it.
black, prince and clear theme's are both messy on custom preview, when using it just save and refresh. it will go back to normal.
