In posting a reply in the Miscellaneous section last night I somehow created a second post that was really messed up. Upon looking at it now I saw no Edit or Delete links that your described. Then I realized I hadn't actually completed the final step to post it, so while I was seeing it, probably no-one else was. So I just had to highlight all the content and hit my delete key. I then really did post a Test post and then found the edit and delete links you described (since that one really was posted) and then I could delete it.
