I think if it's "favourite" there shouldn't be that many, and 6 seems like a lot already. A bit like your besties, it sounds odd if everyone is your bestie, then you really don't have any bestie 😉
The main reason I've restricted it to 2 entries is to avoid people writing about their 'favourite' posts every week and it becomes spammy and loses the challenge's objectives
I will be doing other challenges in the community going forward, so there will be opportunities to revisit old posts, but maybe from a different angle.
Ohhhh that’s nice, thanks for explaining😃
You could also use this new community to publish a challenge called by you: “The three posts you like the most from a certain user of your preference”; and why not “the three worst posts you've ever had” or “Share a post that catches your attention the most from three users you follow”.
Those are some very good ideas. I've deliberately named this community in a loose way so I can adapt it for other challenges going forward. Thanks for the suggestions
