I would like to suggest that you do away with or at least put a timer on the edit function. Many other forums have the timer. You only get a certain amount of time to edit your post and then it's locked. I feel this might make people be more accountable for their actions. They might think twice before entering a flame war if they know it cannot be edited out later to cover their ass. The timer would still give guys the option of editing out spelling errors, grammar errors, and even the occasional time they make a mistake and post a CoC violation. It would just have to be done in a relatively short time frame. Not days, weeks, or even months later. This might lead to more responsible posting in the long run.
(P.S.) – I’ve seen some calls for the bringing back of the edit function. I think this would be a mistake for the same reasons. While it would have it uses in the EE, it would not help matters in the other forums.
