BuddyPress.org

i don’t know if it can save you some work, i’ve tested some more:

* adding only one of First/Last name works

* In every case, if from wordpress administration “Edit user” i change the “display name publicly as” to the nick or last name of the user that doesn’t change inside buddypress

I don’t know if this is a desired behaviour or not, so just hoping to be useful

keep on your great work!
