I am looking to start up a free hosted blog service using Wordpress MU. You will need to get things set up to the point that people can sign up and create their own blogs. I will create a design for the main page, which I may need help integrating. It would also help if you could give me a walk through of Wordpress MU and show me the basics (inserting ads that appears on all user blogs, adding plugins that are available to all users, and stuff like this). I am proficient in standard Wordpress, so you won't be dealing with a complete noob. I need this done asap, so if you can do it, post here or PM me. Thanks!
