I wanted to upvote another user's post. When I clicked on the upvote link I got a popup which stated "[user] currently has 537 reputation points. You have the power to influence pyTony's reputation by 4 points."
I felt his assistance was worth more than one point but there was no obvious way to modify the number of points I was awarding. If I want to award more than the default (one point), how do I do it?
