How can you delete a question such as this from the forum?

I asked a stupid question where I had the answer to. I can only edit this question, I can not delete it.
Same here. The Forums support says that you can only edit posts within 15 minutes of publishing, but doesn't mention deleting (besides how moderators can delete).
They still have improvements to do on the forum.
Removing and Editing a post are the basics for keeping any forum clean and tidy.

They should also allow for images and video's, feels like basics.
