I invited a girl  to the site. She was not a member of my tree. And now she is named as me in the list of members of the site.

I added her into my Family tree and wrote in her profile that the girl in the tree is she, not me. But there was no result. She changed her name in her profile, but there was no result: in the list of members of the site there are 2 girls with the name Nadya but withe the different fotos, different emails and surely different IDs. Please help tho change it.

Thanks in advance.

You can remove members in Home / Site members under the "more" action.

Their name seems to take a day or two to disappear from the members list.
