Redmine

I am able to edit an issue comment. I want to give this right to the other users too. But currently there is nowhere a hint that the comment has been edited. The disadvantage is that a user can manipulate a conversation and nobody gehts knowledge of that.

It would be great if I could see how often a comment was edited and the user can have a look to the previous versions. If too hard, the small, but helpful alternative would be, to show the amount of edits and the author/time of the last edit.
