Edu-clean post mode hack.

How can I make the edu-clean do the following.
1. pull only post from supporter blogs.
2. select random post from the supporter blogs.
3. display 12 post.
or
Instead of pulling post it could pull the bio field and the users avatar so the first page would highlight paying bloggers. Selecting the image or more should direct the user to the supporters blog.

I wanted to use the front page as a supporter feature. This way if you want to be seen you need to pay.
