Hi Remus, good to see you around 🙂. All the suggestions you're sharing actually are/were on the table, the current format being an experiment. Currently only 20-25 people engage with it each day, which is okay but still a small minority of active users. I'd love to spend more energy into it but I also need to avoid over investing in something most users care little about (understandably so, I mean this is a penpal website, not a trivia/gaming platform).
Timing and general stats are definitely things I want to add down the road (many can be generated retroactively, too). I'm hoping showing some basic metrics can increase engagement, especially if advertised somewhere on the dashboard or something for those who never venture into the forum (or the chatroom, which again the vast majority of people don't care about).
Long story short, yes to your suggestions, and/but I need to increase engagement and somehow have as many people as possible include trivia into their daily routine to make this feature a success (making the questions/answers multilingual might also help significantly, some people have complained it's English only and feel left out). Improvements to be added sometime before the end of the year🤞️
