I went through the checkout process and had a handful of things to enter (my name, beneficiary names, etc.). Filled that out and had form for review in my email a little while later. Shortly after that I got an email from their staff who asked about the beneficiary (my son) since we had the same name (but different middle initials, which I had left out). It was nice to see they really check the details and the changes were made very quickly. I now have my trust ready to be notarized so I can start collecting stamps. (Thanks Reddit r/NFA for pointing me here.)
