Hi,
Im a newbie here and just like to know how to submit my SITE MAP URL or XXL site map file to Google and other search engines. ???
I have looked around my Serenade theme but can’t find where this file is kept or what the URL might be ???
Help appreciated. Thanks 
I think you mean the SITEMAP.XML file?
If you’ve got the option to 'Generate Search Engine Sitemap ticked in Settings/Advanced (and you should) then RW creates it automatically and stores it in the root directory of your website.
I’m pretty sure that RW submits the sitemap for you - though I can’t for the life of me remember how. If you’re concerned, Google and other search engines have ways to allow you to submit the sitemap manually.
