I've contributed over 50,000 points to the club and I'm still classified as a recruit. I'm still not eligible for most of the CC tournaments and can't get any responses from the leadership.
There are three active "recruits" in your CC, and y'all joined since December, 2022. Another player who joined in November, 2022, is a "member". This may mean that there is a month of probation(?)
It astounds me that you are excluded from tournaments, since eligibility - AFAIK - can only be managed by tier. Would that exclude all 20 Masters in your CC, including 3 Veterans?
Perhaps, your CC's forum is a way to communicate between members and echelon? Be active, then ask your questions...
As a last resort, you have three active (and two less active) Directors in your CC. Any of those may be responsive if the owner is occupied elsewhere(?) But, he and only he can change your status to Member.
The very last measure would be fo leave the CC, perhaps after a Good-Bye note in the forum(?)
As a general advice, I would get in contact with the Owner BEFORE asking to join any CC, as his activeness is paramount to CC life.
