OK, I followed the steps.
So now, when I go back to reseller level and click nameservers, I see IPs, and I see the main domain name showing in the drop down menu, but I don't see the reseller that I set up.
Please tell me what step I'm missing when I want to "add a reseller and assign them private nameservers":
1. Create a reseller in Admin level.
2. Go to reseller level and click Nameservers to create 2 new private nameservers.
But as I said, I don't see the reseller in the drop down menu.
Sorry for being daft on this - for some reason, I have a tough time grasping all the concepts of DNS. I appreciate your help.
