I'm very comfy with WP, have been using it since v1.7 or so, upgrades, moving from one server to another, plugins, modifying code, etc. I have a client who's needs may fit that of WP MU though. Their goal is to do something similar to HYPEBEAST. Online Magazine for Fashion and Culture - where many people have blogs, all contained within one. I can't seem to find any real documentation on installation though, as it is clearly setup differently than a standard WP install. Additionally, Google hasn't helped me much in the search for themes specifically for MU, should I assume that I'll have to get one designed just for it?
