See Merging duplicate accounts.
If only one profile is an "active" account profile, i.e. has an e-mail address and password, do the merge as you normally would. Enter the two IDs here.
If both profiles are active accounts with e-mail addresses contact email@example.com.
Just merge Davison-2377 into Davison-2360. For more information see
Yay, it worked. Thanks everyone.
Now to the other question:
for some reason some of the profiles of my family which I have created, have a black security rating on them.
I would like to amend all my "black dotted" family profiles to an editable red dot security. Is that possible?
