I have been a member of the Yovia group for a long time now and they are a great way to fill in the holes of your freelance writing income. They pay on the 10th of the month and have a payment threshold of $50.
Usually, I don't deal with people who have a payment threshold, but I almost made the threshold today after 30 minutes of work. It's quick money for writing blog entries, posting Facebook photos and networking.
You can also sign up for a lot of free stuff, too.
Give it a try and tell me what you think in the comments.
