I work at Postloop. Yes, it’s not a lot of money, but if you play it right, it can help supplement your other work. What I do is to take on only forums that I actually enjoy and know the topics, first of all. I just work on it when I need a break from my other activities and don’t make myself do a certain number of posts. That way, it’s more like fun for me, that happens to earn me some extra cash.
