To have WPMU or forthcoming WP 3.0 as a alternative to Joomla at the moment I need this:
1. main site, like a magazine
2. three blogs with menues and everything around from main site (1). So no individual blogs, but blogs as a part of the main site.
It is easy to get 1 to work fine, but I really can't find a good way to use blogs inside the main site in a good way, since all things points towards that the blogs have to be individual sites. Of course the theme can be the same, but that's not full integration.
Is there any other way?
