I've made a new WP installation in a subfolder /blog, set up with "Post name" permalinks.
I'm ready to make several other non-WP website PHP pages which would reside above the /blog directory.
I was wondering - is there a way (1) to make these non-blog pages above the /blog directory have "pretty" (aka "search engine friendly") links (like the /blog pages would have), and (2) if that is possible, is there also a way in WP to somehow disallow using the 'above the blog page' names for WP pages or posts, so that they won't conflict?
