I have a dynamic website that differs for each client  (example:  [ External links are visible to forum administrators only ] - is the address for clovis.  [ External links are visible to forum administrators only ] for bakersfield.   

I need a sitemap for each client's version.  Can I just use different file names for each sitemap, or how do I do this?

Thanks!
Well, you can create multiple sitemaps, specifying different Starting URL each time.
