My in-game name as it is, is "Yyelo". This was the name I called my self back when I bought the game. Recently I have begun putting a "Mr." at the beginning of my name, so it reads "Mr.Yyelo". The name differs depending on the username limits per website, so it could be any of "Mr.Yyelo, Mr Yyelo, Mr_Yyelo, MrYyelo" etc. but it is essentially the same. Hence I would likely put a "Mr" at the beginning, and leave it at that. Depending once again on the character restrictions that would be in place. Ideally, it would be "Mr. Yyelo".
But isn't that too similar to ImmortalHD? The minecraft gamer on YouTube?
