Reputation- How do I give reputation?
When will this be fixed?What if I don't want anyone to see my reputation?
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.
On top of this why do I not know or even see who has givin me a bad rep?
When will this also be fixed?
