Allow forum thread creator to collapse posts
Simply allow the creator of a forum thread the ability to collapse any post within the thread. The post would then be reduced merely to the poster's name and timestamp. Readers would be able to expand posts individually, or to expand the entire thread.
The current forum is not heavily moderated, and allowing thread creators to blacklist posters or lock threads merely gives trolls further opportunity to do what they love best.
This solution would not censor anyone, nor would it create more opportunities for trolling. It would simply allow thread creators to streamline their own thread to keep it on topic and family friendly.
