Remove /blog slug plugin for wpmu allows you to remove /blog slug from the sub directory install of your wordpress mu or wordpress 3.0 multisite.
In the sub directory style install of wpmu, ‘/blog’ is added to the permalink structure, category base and tag base for default blog(or main blog).
Removing it is quiet easy. If you don’t wish your posts to have url like http://yoursite.com/blog/somepost-goes-here and want it to look like say http://yoursite.com/somepost-goes-here, I have an easy solution for you.
