All, Because I have the domain mapping plugin installed

Hi All,

Because I have the domain mapping plugin installed I want to SEO the mapped domains and start by generating individual sitemaps.

eg.
Mainsite.co.uk - Sitemap works as normal
subsite = in subfolders
mainsite.co.uk/site2 but this is mapped so the domain name is site2.co.uk

Because I am submitting site2.co.uk directly I want to upload a sitemap for it but where do I put it?

Thanks for any help
