We don't issue passports on our world, and I don't like any kind of local approach. If we're talking about belonging to the resource, we can set a limit on the number of games played in a season (let's say 5-10 games is enough for a person to have a good understanding of HW).

Ah, another document check. And I don't have an HW passport either; I'm registered under one nickname on a dozen forums. Why try to slow down the process of unification? It's only beneficial for both the people and the game. LeBron is one of the strongest players on our (heroesworld) resource. He plays, communicates, and discusses things much more (and better) than many "people with passports." If he wants to stand up for the honor of HW, that's great. Such a player will strengthen any team.
While I was writing, vitalic also appeared. A super team is being assembled!
