getting people:
the leader should assign members of kani to invite users
i can send invitations by message or on game

i am starting now i will invite black belts
but i need a banner saying ((kani invitation))

everyone can invite anyone,
doesnt have to be black belt though

What if we all add in our Signatures "Join to clan Kani"(or something like that) with link to our forum?

wouldnt that make our clan look cheap?
