Sending URL to Yahoo site explorer
 

If I Index.xml sitemap.xml sitemap, sitemap, etc. 1.xml, what URL should I send to the feed to Yahoo Site Explorer? Does Yahoo think the same strategy would work well? I have about 20 site plans, where each sitemap to cover the whole area of about 500 URLs, and I have to go so when I have a really good side. Sent to all this would do better on the Google Webmaster Tools. It would be for me, all 20 maps of the terrain or the map enough to send necessary? What do you think? Please give me your comments, suggestions and recommendations. Thanks!
