WordPress Network Like B2Evolution

Hi all!

I am converting a multi-blog site that is currently using B2Evolution to a WordPress network. The one feature I am not sure is available in the WordPress network is the ability to have a main front to the network that is like a site itself, but which automatically presents the posts that are added to each of the sites in the network. For instance, my B2Evolution installation was called The Boomer Blog, and was located at boomer-blog.com. I had two blogs working there, each with their own themes, administrators, and posts, plus a links blog that I ran. A link that was boomer-blog.com would take you to the main front page where menu links at the top could bring you to the individual blogs. Or you could go directly to a blog with a link like boomer-blog.com/blog6.php.

Is this setup possible with the WordPress network?

Thanks,

Dave
