That would be too much for me, I’m not an wordpress expert, just stubborn and overambitious, I will try next the domain mapping plugin!
Thank you for your fast answer. In my case the root folder of my webpage is already in use, so I wanted blog.domain.com and blog2.domain.com etc., now i have seen that this setup is not supported by the native wordpress network!
