English Advantage is giving away 400 EC to people who link to the site or write a review about the site. You get 10 EC for a link and 20 EC for a review until all 400 EC have been given away. I think it's a little too little payment for a link and review , but it's almost free credits (you have to link to the site so completely free is not the correct term). Read more here.

Michael Talk is giving away 15EC for a comment in this blog which is a little better payment then the offer from English Advantage . You'll find more information about that here.

This is not exactly a contest so that's why I've added another category called "Other free credits"
