I have a couple questions about using WordPress.com themes:
* How do I find out which themes I can modify the logo and colors with (built-in through the user interface of the theme, without having to modify HTML or CSS)? This would include background and foreground colors, background and header images and fonts.
* Do all of the themes available for use at wordpress.com allow this level of customization or only some of the premium themes?
* Does the Premium package at wordpress.com allow this level of customization, or do I need to purchase additional features?
