The forums have been updated again today with a minor change. If a user edits his/her post, there will now be a "View Edits" button. Clicking this button will show a history of that reply/post, along with highlights (red = removed text, green = added text).
If you do not see the button or clicking the button does nothing, please do a "hard refresh" by holding Ctrl and pressing F5. This will clear your cache and force a download of the new image and javascript file.
Hopefully this will reduce the amount of griefers who go back and edit all of their posts.
