Owners get disinterested in the game and quit, just like many players do.
To me, a CC without an active owner is mostly dead.
Some "oldies" may be posting tournaments, there may be life in the forum, there even may be new members, but two major tasks are fixed to the owner:
- changing member status from Recruit, thus hopefully giving them allowance to create tournaments, and
- ending membership of those who quit.
If there is communication between active members, they may form a new CC. Otherwise, the only way to improve the individual situation is to leave the CC and look for an active one, with an active owner!
