@mentions is not part of bbPress yet.

but for now you can use the @mentions feature from BuddyPress and use on forums with this code.

copy this into your child themes functions.php or use a functionality plugin.

function custom_bbpress_maybe_load_mentions_scripts( $retval = false ) {
	if ( function_exists( 'bbpress' ) && is_bbpress() ) {
		$retval = true;
	}
 
	return $retval;
}
add_filter( 'bp_activity_maybe_load_mentions_scripts', 'custom_bbpress_maybe_load_mentions_scripts' );

and i think you would get an email notification from BuddyPress anytime you get @mentioned

for multiple users you can just separate it with a space.
