On posts you write there's an edit button, for a time, at the bottom right of your post. If you click the "edit" button, on the next screen that comes up is a "delete" button at the bottom right of the editing screen. I don't know that you can delete a thread, though. I think a moderator has to do that and you have to ask them. I'm not positive of that, though.
