for example, I have MU running at sitehell.com
my wife now has the sub-domain princess.sitehell.com
she also owns robinprincess.com and would like to set it up so that if you go to robinprincess.com it will redirect to princess.sitehell.com
She would also like to mask it so that it still says robinprincess.com in the browser address bar.
I'm pretty sure this is possible but i cant figure out how to do it.
Do you need this for just a few wpmu accounts or are you trying to offer this as a feature to every user?
If you just need a few accounts to have domains mapped then you could do it manually. If you want to offer it as a feature then it's a whole different situation because you have to deal with DNS management for numerous domains.
just for a few domains for right now and if anyone requests it.
anyone have an answer to this?
