Editing posts

Such a shame we can't edit - no ones at their best all the time, I understand it compromises any responses to thread as being unclear, but there should be a more forgiving format surely, particularly if no-ones responded to post. What I'm suggesting is to extend the editing rights one has to first post in ones own thread to all subsequent posts if no-ones replied & quoted. Whats harm in this?
