Frank – while I am new to BuddyPress (started it on a site today), i think you are working on similar layouts at moment that I am. The file I just finished re-working was “member-header.php” – I had added Profile Fields like Gender, Age, Etc. to display Gender for Example I used:
basically add the name of the Profile Field you wish to display and use the Field Title name you gave it in the format above.
Other than that its just editing CSS and adding text etc to layout. I am still working on many things – its the one area I really want to pop is the Profiles pages.
