I just clicked on the tab "relatives" & glanced @ some of mine & noticed I'm manager of the people I invited here & I thought had accepted, created an account & taken over management of their own profile.
If somebody else's name's listed as manager then you're not done yet. You gotta create an account complete with username & password before you're "done".
You really want to manage your own profile. You can decide who sees it via settings. Then you can fill out as much as you like. You can also decide whether or not your family should have access to edit it. Depending on your age &/or health...you may want to let them.
