CMS Google sitemap submission
 

Very Simple Question.

For Sitemap Submission to google:
Should I submit the individual sitemap urls that are listed in the admincp> XML Sitemap>Rebuild Sitemap>The sitemap will be accessed by search engines via this URL.

There are 4 of them listed in this file. Blog, Thread, forum and cms

Or Should I submit the one that is listed as Index in the file of the file manager where these are stored?

Or Should I submit all 5?
