We’ve usually voted for the clubs we want to do and decided on a schedule together (usually one a week). You can also create discussion topics for the Unbound stories without them being clubs.
Also, you can jump into any Club thread at any point and share your opinion on the stories. They are scheduled for certain days but don’t have an expiry date. They are really just organised discussion topics for stories. You will receive a badge for commenting. We have TV, audio, book, and comic clubs running currently. There’s also a post with each month’s club schedule if you want to see what’s coming up in April.
