Mafia Wars players (lot or all of them at this moment) are no longer seeing the get/help option from their friend's posts ALSO. But you Zynga obviously think that we are smart enough and we do not need instructions for that Facebook's innovation. Or maybe problem is a bit different FarmVille Support is doing their job much much better then Mafia Wars Support.
So, you Zynga has lot of children, and like all children some of them are good, some are not.
Well if they are not payed the same it is understandable.
BRIEFLY: for MW players whose feeds looks different (check bellow images) for help your friends click anywhere on the image.
