When you answer an question you can edit it before five minutes upon answering it,Without it showing everyone what you edited.I don't know if you made it this way purposly but its kinda annoying.There have been many incidents where someone may answer then another answer comes along people tend to:
-Take bits and pieces out of the below answer.
-Edit there answer with unnecessary crap to try an outclass the other answer.
I think it would be better without this because its tends to start arguments and when someone notices it we don't have proof because its before the five minutes and it doesn't show what they edited like after five minutes.
-Less point grubbing.
-Less confusion/I call it cheating.
