How do I change where my domain points using Yahoo Web Hosting?

I am using Yahoo Web Hosting for my domain and hosting my site. I have a site published using site builder. I added a wordpress blog with the domain www.example.com/blog.
I now want to have my site as a WordPress blog only but I want my domain www.example.com to point to the BLOG homepage.
HOW do I do that please???

Thank you!

Karen, the only time our system will automatically set your blog as your home page is during the initial installation. Setting your blog as your home page after the initial installation is a bit trickier, but it is something we can help you with.
