A friend and I are trying out Wordpress, what we want to do is to have multiple blogs on the same site, one on the main page, and a different one under each tab of the main page. The tab navigation on the main page is to be shared across all the blogs. With users, and authors/admins logging in under one account, that would work across all these blogs, with everything following the same theme. We've been working on this for the last few days, on and off, and are just wondering if what we are trying to do is at all possible, and if it is, how should we start this process?
