Want to change the default BuddyPress “Activity” (activity stream) to “Dashboard”, or “The Activity Center”, or anything other than “Activity”?

Here is how:

• Create wp-content/plugins/bp-custom.php, and put the following:
  [code language=”php”]
  // change BP /activity/ slug to /dashboard/
  define( ‘BP_ACTIVITY_SLUG’, ‘dashboard’ );

  // Change the name for the "Activity" tab to "Dashboard",
  // and reference the newly defined slug /dashboard/
  function bpcodex_rename_profile_tabs() {
  // Change "Activity" to "Dashboard"
  buddypress()->members->nav->edit_nav( array( ‘name’ => __( ‘Dashboard’, ‘textdomain’ ) ), ‘dashboard’ );
  }
  add_action( ‘bp_actions’, ‘bpcodex_rename_profile_tabs’ );
  [/code]

• You may also want to change all labels associated by following these instructions: “Customizing Labels, Messages, and URLs“.
