I don't feel comfortable sharing my real name. on Xbox we have the option to show or not show our real name, on lots of communities we can use usernames or nicknames instead of real name, but in Microsoft Tech community, both our username/nickname And real name is displayed.
this really needs to change. add an option to show/hide real name to profile settings:
