At the moment I have two sites of which I did manage to delete the family tree of one of them, but I actually want to delete that whole site and just keep the one that has my family tree.
I cannot find any instructions for this. How to do this?
Go to Your obsolete famil site, click on Your profile name in the upper right half and take Site settings .. General .. Administration and click the button Delete my site.
Note: be sure to be on the obsolete site.
