I ask this because I created 2 add-ons and I are coming up request via email, but at the same time I noticed that on pirate sites was made the request to illegally obtain my add-on then as a further protection of my work, I required of those who interested contact me for MP here on xenForo, but I need to know if that person is or is not in possession of a license, so I ask of you is to put something that people like me iauti spread over xenForo and has a license. A division between the simple user xenForo and the user who has purchased a license, there is no privacy violated or another but just put a sign that says: "User licensed." and this is written out only when a user has purchased the license.
thanks
