Adding a field to Registration page
I have set up SA and all appears to be working fine. I originally wanted to use email and password for log-in, but then decided to change it to username and password. I changed the Log-In page accordingly, and all was good.
But now I realise that I had set up the Registration and Profile pages without the username field. I know I can't go back into the Wizard. I considered deleting all the Wizard pages and starting again, but I'm not sure it's that simple.
So how do I add a field to existing Registration and Profile pages?
