since I was a total newbie to WP even, it took me a while to customize the MU.
But it's done, still need to get content, links etc. in of course, but that is now a cinch.
I customized the wucoco theme for MU [needed 3 c, something clean, quiet and dark to match my cms site].

Also further customized the spotmilk admin http://nanothat.com/adminspot.html see if you like that, I do. It's easier on the eyes.
Am thrilled to be a MU host now.
Specific thanks to drmike for not loosing patience with me.
