I'm on the Board at a 1000 member club. Remember these are VOLUNTEER jobs and professional management skills / technology / process efficiency is probably not in the core skill set of most of the volunteers.
I'm the Treasurer and self-elected CIO. So far, it's a crap-ton of work but fortunately the pay sucks. Feel free to call and complain about my performance and I'll offer you the job.
