I have been slowly building up a blog that I have at the moment but right now, I have been unable to monetize it due to low-value content so I am continuing to build it up at the moment in hopes I will get approved for Adsense soon.
I have made money writing articles for others and their blogs though. I would love to add a proper blog to my forum in time using the Article Management System but that is a little way off yet before I can purchase the addon needed.
