I have two sitemapsgenerators, one for my CMS and one for my forum. Now I tried Gsitecrawler and it creates a second sitemap for the same content (for the cms and forum). Should I now remove the old one's before adding it to google and yahoo, or does it not matter if there are 2 sitemaps for the same content?
If on same domain: Either use a sitemap index file ...... Or scan your entire website and let a sitemap generator program split it up to multiple sitemap files if necessary.
