I typed many variations of my question of how to add WA hosting to a WA domain into the "Need help" field. The only answers that come up are how to host outside domains with WA. I needed to host the two domains I bought here at WA.

Then I looked around in WA at my domains and found it is so easy, DUH! So that's why no one put it in a training! I hope this saves you some time!
