At times like this, it really sucks that we can't remove an article from the submission qeue, edit it, then resubmit it. I can see not allowing edits after an article's been approved, but we should be able to edit ones which are still pending approval.
edit: Looks like I did manage to find a successful way to re-edit the article while it's pending. I don't know for certain if it went through properly, but the title in my pending approval list is now the new title, so it -looks- like it worked.
