That's the same page/form that I was referencing, Kerry. I used the title of the tab that I see on my browser.
Add New Person, which I accessed through the drop-down menu, has the title Add an Unrelated Person on the form page itself.
As you state, the trusted list message doesn't appear on the profile creation pages that we access from a profile when we are adding a parent/sibling/spouse/child.
Even though this message appears on this specific form, I would be surprised if many WikiTreers realize that this is what happens when they use this form to invite others to join WikiTree.
And if this is what happens when invitations are sent from profiles created through the relationship links and when invitations are sent after the profiles have been created, then we certainly need, at minimum, a red alert banner to let us know that this will happen!
