Is there an option to delete threads?

[MidbossVyers]

If I wanted to, where is the button to delete my own threads and posts?

You can't do it yourself. Best way to do it is to hit the report button on the bottom left of the post and say it needs deleting.

Another way you can do is click edit, delete the comment text, and put "Comment Withdrawn"

Both replies are VERY accurate and can even be used in combination.

 

Those are the only two options available.
