I’d like to try to summarize the ideas, if I missed something or got it wrong please don’t post a reply but send me a personal message, so I can update this post and keep it as actual as possible.
1. Introducing a minimum limitation of characters for an exercise submission comment.
2. Adding an amount of pass-votes for exercise submissions to pass.
3. RSVP-system for submission areas.
4. Creating a (new) reward system for community-activity.
5. Scheduling regular feedback-streams.
6. Adding a peer-buddy-system.
