1) No. You can be a great player, or a complete noob. It's how you act, behave, and your actions within the community that defines who you are and how others perceive you. I know some members who are outstanding leaders, get a lot of work done for eGO, and are just fair players.
2) How'd you get your name? I thought the : would be invalidated, much less your forum name should match your in-game name. But if you're in-game name is actually that, what happens when you actually improve and become a cs:s pro?
