Let’s see, are you talking about all the links in the admin menu bar, the member theme or the home theme? It seems you want to know where *all* of them are.

(sigh) Ok.

The admin bar code is in: /mu-plugins/bp-core/bp-core-adminbar.php

The code for the member theme is in: /wp-content/member-themes/buddypress-member

The code for the home theme is in: /wp-content/themes/buddypress-home
