Not everybody knows about clans. There are players who have never played game like this before. And how "everybody" knows about clans? Somebody told them either in chat or here in forum.
I have read a few of your messages. Why do you have to be so arrogant and hostile towards other players? OK, some of the questions are "stupid"(asked many times before), and may bore you, but people who ask them really need that answer. If topic looks boring or stupid to you, don't bother to read it.
Anyways, good luck in the game! :)
