I was having this same problem and after a long mostly fruitless search I finally found a solid/working answer. The way buddypress currently handles these tabs is quite unwieldy so removing each tab requires a different method…

How to remove group settings tab:

function bp_remove_group_step_settings($array) {
	
	$array = array(
		'group-details'  => array(
			'name'       => _x( 'Details', 'Group screen nav', 'buddypress' ),
			'position'   => 0
		)
	);
	
	return $array;
}
add_filter ('groups_create_group_steps', 'bp_remove_group_step_settings', 10, 1);

(reference)
How to remove group avatar and cover photo tabs:
1. go to Dashboard » BuddyPress » Settings
2. untick Group Photo Uploads and Group Cover Image Uploads

How to remove group invite tab:

function bp_remove_group_step_invites() {

	global $bp;
	
	unset( $bp->groups->group_creation_steps['group-invites'] );
	
}
add_action( 'bp_init', 'bp_remove_group_step_invites', 9999 ); 

How to remove forums tab:
Disable forums for buddypress…still havent figured out a more practical answer…

Hope this helps though!

That worked, I knew it was something easy that I was missing.

Thanks!

Oops hit reply not edit! well…

Here’s the solution I arrived at:

function filter_change_email_subject ( $email_subject, $sender_name, $ud ) {
	$email_subject = sprintf( __('%1$s wants to say hello', 'buddypress' ), $sender_name);
	return $email_subject;
}
add_filter( 'messages_notification_new_message_subject', 'filter_change_email_subject' , 10, 7 );

This works for what I’m doing, for someone else that wants to pass a dynamic subject you may need to nest this function.
