'Sitemap' and 'urllist' files added

We've added sitemap files (listings of all the URLs, in XML format) and urllist files to both USRSA.com and racquetsportsindustry.com. These files are recommend to help search engines -- primarily Google and Yahoo! -- better crawl the site, so that when you search for information that appears on either site, you will more easily find it. Ironically, MSN Search, which seems not to pay any attention to sitemap or urllist files, has by far the best index of our site.
