I've just learned of this from Pinoy Money Talk, but some companies pay you to post on forums! The rates range from $0.01 per post to $0.30.
I just applied for one forum I used to participate in. They're offering $0.18 per post, and I hope I'll get accepted!
I'll be researching on other such sites, and I'll post them here. Feel free to share any such companies here. Thanks!
