Double posted a thread on accident, forgot how to delete

I made my 2nd staff app and I posted it twice (again) on accident. Due to my long absence, I forgot how to delete a thread and need help for the simplest thing ever ._.

 

You can't delete threads :I
But most usually ignore the one with no replies.

 

I figured out from a staff member that you can't delete threads so ignore this thread as the problem has been solved
