[XB] Registration Invites 2.1.0

What in the world?
I'm trying to buy the addon but it requires that I renew my xenforo license?
Are you kidding me?

I love it, very useful add-on. You can simply put 1 dollar for registration, or get a code from other users for free. After purchasing the code will be automaticlly filled in the registration panel. All of these features will give a great benifit in the long term for running a forum.
