We have updated the issue report feature for each problem. Every problem now has its own independent discussion thread, where you are welcome to post discussions, editorials, or any other related content in the problem forum. All posts are public, making it easier for everyone to find relevant discussions and reference materials.

We will also use the problem forum to share updates, as well as useful resources such as tutorials and write-ups. We hope you enjoy this new feature, and we look forward to hearing your thoughts and contributions there!
