I have never personally worked or know Kumiko, however I have noticed that she had many achievements especially with the U21 team and had made positive effect towards this community. Definitely a tremendous loss to the community.
Rest in Peace Kumiko.
As for the name change, I personally feel that there should be a poll for the entire country before make that decision. I believe there should be a BB Mail to all members in this community as not many people read or post in the forum. I think Kumiko's achieves and impact should be engraved in the U21 News as she put a lot of effort toward that team. And last I suggest the games should start 5 mins later for a week as a moment of silence to show respect and sadness the community feels if it's possible.
