SEO Sitemap problems!

hi Ryan, I follow the SEO tutorial

2 minor problems

1) I create “google_sitemap” xml type template in “site” template group, but! if I run mysite.com/google_sitemap dont load!... they load to the homepage… so for run I need put mysite.com/site/google_sitemap

why I need put /site/ ?

2) ok I run firefox mysite.com/site/google_sitemap and show the xml but not like in safari like the tutorial, in firefox say:

“This XML file does not appear to have any style information associated with it. The document tree is shown below”

that is bad????

ok If I run on safari… great show like the tutorial BUT! show everything line beside line, I mean not the tutorial (like with a
) you know line enter line enter line etc… that dont affect I think, but what happend that?

really thanks!
