How to add reputation star button

[caciocode]

I am not sure whether this is a mod or just a setting I have to set. I would like to add a reputation star button on this forum just beneath every member's post in the forum which will allow other members to click it. How do I add this? because I really need it. I have seen this done in many other forums.

Thank God I've found this forum, because I have more questions to ask.

Thank you.
