I would reduce membership to a level of about 3 spots per hunter. So if you had 6 in on the lease you'd need a minimum of 18 stand sights. If you can only support 15 stands I'd go down to 5 members and so forth. Forget anyone ever told you a 1 per 100 acre rule.
Get rid of people who have too much time to hunt. Get rid of all the doe killers. Get rid of all the people with kids that need to shoot something every time they go so they won't get "bored".
Then stop calling it a club and people will stop asking you if they can join. They'll be asking. You'll have a real nice place at that point.
