Removing namespace in developer org
When I was practising Managed/Unmanaged packages, I created a managed package and deleted it. Currently I dont have any packages created in my Developer org. I would like to delete the namespace now completely from the org in all the componnets. Can you please let me now about it.
So far once if you registered your namespace then you can't remove/edit it.
It's unique across all organization.
