Carol, it's great that you are improving the profiles. On each of the profiles you edited and need to merge, click on the REQUEST TO BE ADDED TO THE TRUSTED LIST link. It's right under COLLABORATION on the right side. You can also post a small message on each profile that you want to be added to remind her but it also let the wikitree management know that you have asked to be added.
She will automatically get an email that she clicks on and you will be added automatically as profile manager to do the merges into the right LNAB ( last name at birth).
If she still can not figure out how to add you, email Paul@wikitree.com about this problem.
