Hey thanks for the reply, though I looked that up myself but thanks anyway.
Right I manage to get the domain mapping working on my local server, but I can’t seem to get it working on my live site at all, not 100% sure what I am doing wrong, Here an image of my settings and etc..
Right I got two test sites up and running and it seems to work, the only thing is, is that my real sites will take a good few days for me to be able to get everything up and running on a wordpress MU network and for me to completely get this sorted in this way.
I am wondering if there is any quicker ways then this?
If not then I am going to have to re-install my sites and get everything back up and running, which will be an pain.
