Hi,authorized person. I would like to join this tournament from Turkey at Open Category. I have just been a member of ICC.
Can you give me a list to do by me? Do I have to pay fee for all tournaments? And why ?
Are prizes payed from fees of players at tournaments ,aren’t there any sponsors or any other things?

Best rgds,
