If you click on the top root link in the CMS, you can add the site title, tagline + choose the theme.
I'm setting up a site which will be duplicated for many clients, and I would like the client to be able to hit this 'settings' page (as i'm calling it), and in addition to those 3 options, I want to let them upload a company logo, choose a page background colour, and a few other options to customise their site.
Any ideas?
