Thank you for fast and helpful answer. I have seen display names mentioned before but I did not understand how to use them. I now found I can change my display name in my profile and chose my full name or parts of it as display name.

I have not yet tried to integrate a WordPress web site with a bbPress forum. Is it now possible to let users log in once to both? Or at least use the same user name and password for both? Can the display name option be used in both?
