Re: unsupported file format

Hi there
"unsupported file format" probably refers to the Google Sitemap file it
is trying to find. Can you show us the URL you submitted with the
sitemap file to Google? Then we can check.

The other messages, errors, etc. are with regard to your site in
general, and are not dependant on a sucessful Google Sitemap file. Page
rank is determined by Google based on the number and value of links
pointing to your site. It's nothing to get worried about though :-).
Here's something about pagerank:
