I haven't read all of the SEO advice given in this topic, only the responses regarding the 301 issue I mentioned previously.
Here's an article that touches on the 301 index redirect issue:

Quote:
WordPress blogs show the same duplicate content for http://www.askapache.com/index.php and http://www.askapache.com/. If you’ve read about using a robots.txt file for WordPress SEO, than you already understand this setup results in Duplicate Content penalties being levied against your Blog and Web Site by Search Engines.

Quote:
Be consistent: Endeavor to keep your internal linking consistent; don't link to /page/ and /page and /page/index.htm.

This is an issue where it isn't going to harm her by adding the 301, but most certainly can help her. Why not do it?
