I wouldn't do a poll, Sheryl. I would hate for it to discourage anyone. While we have a lot of members who check in on RC and a handfull that post, the poll wouldn't give an accurate representation of how many are reading the newsletter.
One of the goals of the newsletter is to make sure people who aren't on RC get the information about the club and meetings.
I took notes for one week and discovered that we have about 30 members who regularly check this forum. That's not a bad number and makes for good conversation and community, it is only about 25% of the club. On the other hand, when you send out the email, you reach 90% of the members.
I think the newsletter is a really important means of communication even though it is often a thankless task.
