Hi Bruce. Could you explain what you mean by "add to your trusted list"?
The following is important:

It says:
If I add you to my Trusted List can you access every profile I can access? No. Every profile has its own Trusted List. As a WikiTree user, you have a profile and your profile has a Trusted List. People on this list can access your profile but they cannot automatically access other profiles you have created or edited. Those other profiles have their own Trusted Lists.
If I add you to my Trusted List can you access every profile I can access?
No. Every profile has its own Trusted List. As a WikiTree user, you have a profile and your profile has a Trusted List. People on this list can access your profile but they cannot automatically access other profiles you have created or edited. Those other profiles have their own Trusted Lists.
If you can please expand on what you actually want to achieve, it will help us to answer your question more precisely.
But briefly, to add another WikiTree member to the Trusted List of a profile, you need to enter their email address in the appropriate box on the Privacy tab of that profile. There do exist tools for doing this to a number of profiles in one go.
Further to that Bruce, if you want to add a family member who has a WikiTree account to the Trusted Lists of several profiles you manage all at once, the relevant bulk tool is

It may be a good idea to try it out with a small number of profiles only to start, so that the recipient member does not feel swamped :-)
