Me thinks, it costs big time!
At first, you have few members, and you will be the general dogsbody, setting up tournaments, keeping the Forum alive, inviting and instructing new members.
You want a homepage? You do it.
Tournament series need a lot of attention - you do it!
Members wanna know? You answer.
Members want ...? You do it or observe it closely.
The most nerving detail may be that players come and go in this game on short or long term, but they stay members regardless if they joined. Wanna live with sleeping members, or compliment them out?
And, as a small CC, you have to care for the $%&§$ CC levels (patience vs. credits...)
With more members, it may be easier. I inherited a 250 members CC a few years ago, and I let it take an easy course. 60 players are active playing, 30 are actively interested in our activities. They run two projects by themselves, but I still have to show the lead, collect ideas and organize things: After our first CC Championship last Winter we are now in a 12-week Tour event with Handicap scoring, and in the community Davis Cup competition.
BTW: In addition to 180 inactive members, there was a fluctuation of about 160 members in 14 months ;)
