BuddyPress.org

there is a way to edit the users data, i have a plugin installed that allows you to go to users and then click a link and it logs you in as the selected user, obviously this means you can edit thier profile, the link only shows up for the site admin

the plugin is: user switching – https://wordpress.org/extend/plugins/user-switching/

the only annoyance is that once you switch users it means you must login again to get back to admin or watever, i.e. it doesnt allow switching back and forth between accounts

it does help greatly though, hope this helps you
