How exclude the author from signing a personal message? I found the two functions are responsible for this:

function get_recipient_links($recipients) {
if ( count($recipients) >= 5 )
return count( $recipients ) . __(' Recipients', 'buddypress');

foreach ( (array)$recipients as $recipient )
$recipient_links[] = bp_core_get_userlink( $recipient->user_id );

return implode( ', ', (array) $recipient_links );
}

function bp_get_the_thread_recipients() {
global $thread_template, $bp;

$recipient_links = array();

if ( count( $thread_template->thread->recipients ) >= 5 )
return apply_filters( 'bp_get_the_thread_recipients', sprintf( __( '%d Recipients', 'buddypress' ), count($thread_template->thread->recipients) ) );

foreach( (array)$thread_template->thread->recipients as $recipient ) {
if ( $recipient->user_id !== $bp->loggedin_user->id )
$recipient_links[] = bp_core_get_userlink( $recipient->user_id );
}

return apply_filters( 'bp_get_the_thread_recipients', implode( ', ', $recipient_links ) );
}

How can this be done and put into the file bp-custom.php?
