Weird… I have one user where only the login name is used, but another one where the display name is shown. I’ll come back to that if I find out what the difference between those two is.

But in the meantime, another problem arose: How do I access the login name when the display name is shown? I need the login name to build the link to the user’s buddypress profile page. Is there a template tag which (always) returns the login name?
