One of the first setting I changed when preparing my group was to not allow users to edit their posts. Not only do you get into problems such as you describe, we've had instances (long ago) where it caused problems with "who said what when"? - and it wasn't pretty. It's sad to think that editing? could be used that way, but it's a reality.
If a member needs to edit a post due to an error, they will usually post their own correction, or they can send a request to me to edit it for them.
