Hi Oleg,
Perhaps you can help me.  My website has about 6000 pages or photos.  The Sitemap generator uses about half of my generated page space pages on prices of individual items for sale in a database.  This is an aspx database and over 300 simple prices are listed as individual pages.  I don't want these items listed.  It misses important other pages.  I've tried to use the dashboard to stop listing errant pages, but with no success.  Can you please advise.  Thank you.

could you please PM me your generator URL and an example URL that is not included in sitemap and how it can be reached starting from homepage?
