Regarding your attempt - I respectfully submit that anyone can make a mistake. I know I have often thought I posted something and found it is "no longer there" when the plain truth is I probably hit the wrong button.
When you check to see your contribution is in place, see that it is, but it is not there on a subsequent visit - I respectfully submit that this was NOT the case here. It was not a mistake on my part.
The adoption of my suggestion would at least ensure that if posters did not see an editing comment of explanation - they could be sure to rule out and get paranoid about imposed censorship action being responsible for the non-apperance of their contribution.
Often this appears to be many poster's first assumption.........As this could be so easily be addressed - I can't help wondering why it is not. Unless the intention is to make our forum totally paranoid about possible censorship?
