Whenever u post on this forum there will be a "+" and "-" next to ur post similar to facebook's "like"-button. The difference here is that u can also dislike someone's post.
U will gain 1 reputation (good or bad) for each "+" or "-" u get.
Reputation-meter will show under ur nick.
Also there is a "thanks"-button that grants 3 reputation points.
Peace, love and haters
