Change main blog

I'm using BP-Daily for a site that has multiple bloggers, each with their content on their own blog using WPMU 3.0. I'm wondering if I can easily change the main blog from Admin to one of the more interesting content providers on the site, since the Admin doesn't post content for public consumption? As it currently stands, I am using Autoblog to get content on the front page of the site. It would seem more efficient if I were to have a different blog be the home blog. Many thanks in advance for your advice.

Cheers,
Paul
