I like the updates you do on facebook as the messages pop right up on my home page. I don't have to go and check them. I rarely check this board, but I check my status updates on facebook every day to see what my friends are up to, so keep up the good work there. Scheduled group chats might also be fun on facebook. And it is so easy to share photos on facebook.
Meetup.com would be great for forming local chapters of the club. Maybe you could charge a nominal fee like $20 per year for each chapter if they would like to use the WFFCC name. I always try starting a club here, but just using e-mail isn't an easy way to get together so I am launching a meet-up group for it later this summer.
I'm with you on the security thing, if they want my info they can find it anywhere on the web. My Mom will not order anything on-line (uses a manual order form - if they don't have one she doesn't order), she will not use a debit card, and she will not give her phone number to her rewards cards. She thinks this keeps her off the grid. Silly woman. I keep telling her all the companies have her info computerized, including her checking account number.
