So if someone is mad at you,,they can go pee in your canteen? Not a good thing to my way of thinking and needs to go bye bye,,,,,I may not like somebody but that is between them and me and should not reflect on their general reputation unless Admin hands out the demerits.
You can disable the display of your reputation by going to your User CP and selecting Edit Options. On this page you will find a check box labelled 'Show Your Reputation Level'. Un-checking this box will remove the display of your reputation and replace it with the Reputation Disabled icon. You can still give and receive reputation while your reputation display is disabled.
Think I will disable mine, I know who my friends are and have NEVER given anyone a reputation rating.:crymeariv
Personally I'm not sure I see the need for it...with the possible exception of informing new forum members. An active forum member with any time here has a pretty good idea of who he's listening to and who he/she's dealing with....
