I am creating a website using WordPress and am wondering if it is easy to display posts and also the archives of posts (IE /2010/09 etc.) inside a seperate directory towards the relaxation from the site.

Example:
domain.com/blog/this-is-a-blog-publish
domain.com/blog/2010/09/
domain.com/about-us
domain.com/items

Does anybody know if this sounds like possible, or has been doing this before or point me somewhere which has, I'd be super appreciative.

So apparently it is possible with a combination of mod-rewrite and taking advantage of a couple of pieces came from here: http://codex.wordpress.org/Creating_an_Archive_Index
