SEO

I have a simple 5 page site with pages index.htm about.htm contact.htm events.htm directions.htm I want my web addresses to all be http://www.mydomain/about ... for each execpt index just / for that I've been looking into using rewrites but seem they are all complex and full of things I don't need Sera

For months now I've been wondering why search engines keep getting raw (non opensef) links to my sites pages, finally realized it was coming from my RSS which isn't using the sef urls. Could I manually alter the rss output to fix this?
