I’ve been looking at the multi-user version of Wordpress - Wordpressµ. The idea being that if blogging software can be used to create content-managed websites that don’t look like blogs, multi-user blogs should be able to allow for large scale content-managed sites. These sites could have many subsites (sub-blogs) with their own identities and management systems. Perfect for, say, a departmentalised organisation. Each department could have its own branding (logo, colour scheme etc.) as well as its own contributors and moderators.

Wordpressµ does this really well. I played around with it (even making my own theme - the look and feel which gets applied to each blog) and pretty soon had a skeleton site up and running on my PC which featured several subsites, each with the ability to customise the look and feel for that bit of the main site. I also created different levels of user from contributor level to super-admin.
