Sharepoint 2010
Is this correct that every site has its own v4 master page? and every site collection has one v4 master page (all the sites in collection have one master page)?
I am developing document library and site collection has got only one site in it. I have made some changes to v4 master page and wondering if these changes would effect the new collection sites? I think when you create a new collection site then Sharepoint creates a new v4 master page for this collection site?
