How to add email on a existing member profile?

Thank you Anderson but it only appears the new profiles added, not the old ones...

If a person has already accepted the invitation, and they changed their settings so that nobody else can edit their profile, then you can't add another email address in. To be able to tell if they have claimed their profile, you'll see a blue outline around their "node" (their block on the family tree with their name on it).

If that is not the problem and you think there's a "bug" you can contact Customer Service.

Thanks! Will check...
