Sigh. No, I don't want to edit or delete an OLD post. Sorry, English is not my natural language.Maybe I'm misunderstanding. Is there an old post that you want to edit or delete?
Sometimes when I reply to a thread/post I find out that (within 30 minutes) the answer is mistaken. Then I can't delete the post, only edit it with nononse text.
What if the new post is the 1st post in the thread,there might be other posts that follow the 1st post.
