I’m interested in this bit here.
First of all how do you define for your specific forum when a topic is “dying” (what metric do you use, no new post in x days for example).
How do you go about reviving a dead topic “aggressively”? By having members of your team make new posts in that topic, pinning the post, redirecting traffic to that post?
After a dead topic has been revived but dies again do you repeat the process to revive it again?
