Jaxel's sitemap generates the individual sitemaps you build in xenutiles options and puts them in yourforum/data/sitemap/ folder but the xml file will show up on your forums root. So basically, after you install the modification and generate your sitemap, your new sitemap is yourforum.com/sitemap.xml You enter that url in the sitemaps section of Google and Bing Webmaster Tools. That sitemap is then generated every couple days or so by a cron so that you don't have to mess with your sitemap ever again!
