If you already have a blog, and need to earn a little money, perhaps to pay for the domain name renewal, or your hosting costs, may I recommend you check out Bloggerwave some time soon?
They currently only have a couple of opportunities to earn money - this sort of post and another, but as new bloggers join up, I’m sure they’ll get new opportunities. It only takes a few minutes to sign up, and I was approved the same day, so what do you have to lose?
