Unluckily I don't have much experience in organizing tournaments so please, feel free to send me a message with your comments if you see something that could work better.\n\nIn terms of Handicap, I think we still need to discuss about it since we have a huge variety of ranks in our beautiful group.\n\nGood luck to everybody :)",
