Click on "Edit profile" then scroll down the page, and underneath where your subscribed threads are listed will be your reputation section. Should be titled "Latest Reputation Received". If this section isn't showing up, maybe it's because you hadn't got any rep at that point? (but you do now as colliemerles left you some!). I do think that when you first join the forum, you automatically have 1 green rep square. So already have a few points, but they aren't left by anyone.
