Every Sunday evening.
Interesting to make some sort of a voting system, perhaps. [what is found below is a try-out]. There is a weekly screening, and (just an idea!) a monthly more public screening (e.g. called "Camera Obscura"). Not sure how we'd organise the latter, cause we can't host 50 people of course - unless we mount another screen and beamer in the living room but that's probably not as cosy, and simply too much of a good thing. The cellar is probably not great for that either.
Add last edition's score, add history of all films we've seen together, perhaps even with a rating and some comments.
