Here are the copy-pasted instructions you get when you access your domain manager:
Learn how to manage your name.
1. Set Resolver
The Resolver is a Smart Contract responsible for the process of translating names into addresses. In the Resolver area click ‘Set’. Then click the ‘use public resolver’ link, and ‘save’ to launch the transaction.
2. Set Address
Once you have set the Resolver, you can then add records by clicking the ‘+’ in the ‘records’ field. Adding your ethereum address will allow you to point your wallet to your name in the next step.
I’ve made a subdomain. I’ve set the public resolver for both the domain and subdomain. I cannot set address. There’s no place to add records. There is no ‘records’ field. There is no ‘+’ anywhere. My wallet address appears defaulted in the Controller field. But the domain still doesn’t point to my wallet.
Does it take 24 hours, or something? What am I missing?
Then, there’s step 3. I haven’t gotten to this step. Can I ignore it if I don’t want or need a reverse pointer?
3. Set Reverse Record
Once you set your address, you will see a message saying the reverse pointer is not set. Click the arrow in the field to expand, then click the button ‘save’. This will translate your address into your new name.
