Second post, so I guess this is a little backwards

Been reading around the site for a month or two now, and can't get enough. After my first post this afternoon, I was rooting around the site a little and was reading about the wso credits. On the page it says there are three ways to get credits and the following section goes on to explain only two ways. Now, I could be missing something or there is some mysterious third way that I can only learn from the sage users here at WSO, but either way, I'm going to continue on my way enjoying the site!
