How do I delete my thread?

Please i created a thread of which i want to delete, can someone kindly help me how i should go around it? thank you.

Is it a thread or just a post? You can delete the latter but not the former

Its a thread, if it cant be deleted is there any option where i can change its title?

If its recent you can change it in “edit”, otherwise you need to ask the moderator to change it for you
