Forums
The website has two purposes: 1) to serve the club members and to bring the club together; 2) to let the outside world know what the club's about and to attract people to join.
The latter purpose doesn't necessarily require open access to all content (for example the forum and comments are already hidden from the outside world).
One possibility would be to restrict access to news articles, say, 3 months after publication, when they'd become visible only to authenticated users.
I wondered if anyone has any thoughts or concerns on this matter?
