Post editing is a simple function. Many forums allow editing even after a response has been made. I've only ever seen one poster claim that editing a post is actually a weapon aimed at him.

Jim Nelson apparently has experience in this area, after you-know-who laid a complaint against him after he edited a post. Apparently UT was able to go back and check the original content and reprimand Mr Nelson. I have never experienced any such reprimand myself, which possibly casts some light on the veracity (and motivation) of the latest claim.

Your facts are incorrect, casting a much brighter light on your motivations.

Unless you want to pursue this further [which would NOT be in your interests], put a lid on it.
