Deleting posts and threads?

sure it must be possible, just can't find the option for either of them, any help?

You can request your thread/post to be deleted by asking a minion of that section

awesome thanks

and also, any idea as to when i go to edit my thread, it can't be edited, i mean, it just comes up with a blank box like this, even though there should be content there?
