Sometimes it is best just to show up at the club on a weekend when you know someone will be there or find out when the meetings are and go to that. Most club officers are volunteering their time and may not always be available to return e-mails and stuff as much as they might like. Also, I hope this doesn't come off the wrong way, many of them are older retired guys and they may not necessarily be the type who is online checking e-mails regularly. In some cases a good old face to face meeting/introduction is the best bet.
