Hi! :D A normal human being absolutely can fit in our game. Even if you don't have powers, there will be future opportunities for them to gain powers if they want them! ^^ And since the game is set in an original universe, you don't have to know the canon of the other casts really (well only if you want).

The applications being sent through email was a decision made by the head mod - I believe he just prefers it that way. I personally find it easier to be done through the comment system. They may change the way they have applications sent in in the future though :)
