Notification for new successful invitation

A small but valuable improvement for the invite system would be adding a real-time notification when someone joins successfully through a user’s referral link.

For example:
“🎉 John Doe just joined WPFolks using your invite link.”

This gives the inviter clear confirmation that their referral worked, adds a rewarding feedback loop, and encourages them to keep sharing more actively. It would make the invite system feel more engaging, motivating, and transparent for users working toward affiliate and community badges.
