I'm not sure if I should be inspiring people to do this but:
On slow boards you can become something like a janny.
If there is a thread you dislike, you can reply to every thread underneath it then create a new thread. This will archive the thread.

I'm sure some of you have already thought of this but it just popped into my head while I was brushing my teeth and I decided to try it out on here.
I picked this thread (pic related) at random because I didn't want to delete a useful thread and I didn't want something too near the bottom. It was previously on page 7 I believe.
With the creation of this thread it should have disappeared, never to be bumped again.

So long little thread, I hope you had a good life.
