How do I delete a thread?

I could've sworn I've seen a delete option somewhere on the posts when rping but now I can't find it anywhere. My internet glitched and posted the same thread twice for some reason. 

Link to the thread (one of them anyways): click

You can request in the Maintenance thread (in the Help forum) to have the extra removed, for future reference. :)

Ah, okay, thank you!
