the board typically sends out a broadcast email message once a month. it's fire and forget. a concern i have is that recipients don't pay much attention to these email updates. personally, i'm on many organizational email lists. i don't pay much attention to any of these emails because they are not part of a conversation. i do pay careful attention to communications that i can respond to.
so, as far as participation goes, the messages posted to the forum are far more useful than the monthly broadcast messages. they are conversations but, in general, everyone who registered before march 2011 (the vast majority of members) do not receive notifications of the messages. people who registered after march 2011 do receive notifications.
for instance, it is clearly a good practice that notice of board meeting minutes is posted to the main forum. the idea is that people will be informed and can comment on the decisions made. however, the vast majority of the membership are not included in this notification, therefore, unless they happen to log into the site and notice the forum post, they will not have the opportunity to participate in this conversation.
it seems like a no-brainer that if we could go back in time to the beginning, enabling email notifications for the forum as the default setting would have been a better policy (it's the policy we're using now for new members and none have complained). people can turn it off if it is too much.
however, switching everyone to forum notifications without their consent is almost certainly not a good idea.
we've recently had conversations about imposing a cost for inactive accounts. one thing we could do is have a policy that if you haven't logged into the site in a certain time period (6-12 months perhaps), your account is disabled/expired. you will receive a notification when your account is disabled and there is an easy, automated form to reactivate, but when reactivated, you receive notifications by default (the policy for new memberships) and you can, of course, easily change the setting to turn off forum notifications.
