Yes. I think what you mean by setting up a server is something like hostname: new.mynewdomain.com. I did that.
So now I have an empty mysql database. I set this up before the new domainname server may have pointed at DH, but I was able to access the empty db. I deleted the new db and I set up another one, which I am waiting for to become live.
How does one get out of phpMyAdmin properly? I try to log out and it asks for my password again. I seem to be in a loop.
