Unlimited Generator picked up on the site's htaccess, with the 301's listed and also the meta noindex pages, excluding both of these page types entirely from the sitemaps.
After a major redo on the site, which has only been this way for two days now, I'm wondering if I should wait to link the sitemap to Google (webmaster tools) until Google can see the individual pages getting the 301's and meta noindex pages - even though Google was pinged I assume the sitemap must first be linked first for G to detect it? - But then again there is Yahoo and Bing. Too, there are 3-4 pages having meta noindex within a large excluded folder.
From what I understand, rpc.pingomatic.com/ address provided is only for blogs, right?
What if the site has dated user comments/forms? Is this needed? Or updates on these be detected without it?
Also: Is there a way to delete a sitemap that is run or are they simply overwritten on each run?
