Events, with date and place. Some need signing up and have limited places: if you fancy it, sign up early, because it closes on its own when full.
The association archive, by year. If the committee allows it on a gallery, you can upload your own: they arrive pending and somebody approves them before they show. Not censorship, just avoiding duplicates and blurred shots.
Set the year when you upload. That is what makes them findable in ten years.
A game built from the association photos: eight come up and you say what year each is from. There is a leaderboard for the month. One minute a go, and more addictive than it sounds.
The constitution, the internal rules and whatever the committee publishes. All here, searchable, so nobody has to ask for it again.
