OK, this is going to be a tricky question to ask because of the lingo.
But my problem is not to do with domain mapping with MU set up with Subdomains. But I want one of my subdomains to be mapped to a subdomain of a URL I own.
I have cookingclub.kitchlondon.co.uk (WP Multisite subdomain)
I also have a shop here http://www.titchykitch.co.uk
I want to map the 'cooking club' url to club.titchykitch.co.uk
Do I need to set up a subdomin with my cPannel? Or is this all done through DNS?
