Hello Jim
Not a dumb question. Work is going on to move the NBN Gateway to the new version and so the "top copy" is now the new database and not the old one which is the reason why no more changes can be made to the the old site.
It was originally planned to allow login to the new site on release so that changes could be made through the new site but a number of last minute issues has meant that login has needed to be disabled on the new site for now. Work is going on to resolve these issues so that login can be restored for the new site, within the next few weeks
Best wishes
Graham
NBN Technical Liaison Officer
