Okey, sure!

Core features

• You got a personal message from “John Doe”
• “John Doe” wants to be your friend
• “John Doe” replied to your group forums thread

Popular plugins (These would be amazing to include)

• Buddypress Like – “John Doe” liked your blog post
• Buddypress Followers – “John Doe” started following you

I tried to setup the notifications by myself but it’s not working (blank page). I used these code snippets in the bp-like.php file inside the plugin folder (adopted from Buddypress Followers plugin) . If you want to help me and understand how to set it up, I will pay 20$ through PayPal.

function bp_like_setup_globals() {
	global $bp, $wpdb;

	// For internal identification
	$bp->like->id              = 'like';

	/* Register this in the active components array */
	$bp->active_components[$bp->like->id] = $bp->like->id;

	// BP 1.2.x only
	if ( version_compare( BP_VERSION, '1.3' ) < 0 ) {
		$bp->like->format_notification_function = 'bp_like_format_notifications';
	}
	// BP 1.5-specific
	else {
		$bp->like->notification_callback        = 'bp_like_format_notifications';
	}
}
add_action( 'bp_setup_globals', 'bp_likesetup_globals' );

Sorry, I don’t know what was wrong. It works now!
