A review of Enroll/Improve the Web site
A registration test brings you 0.40 dollars + 0.10 dollars bonus and all the other tests vary from 0.10 - 0.20 dollars. And, you can click often on a Dashboard tab, answer a couple of questions with yes and no and maybe receive your surveys sooner.
There is a down side and that is you, when you receive a link to a survey on your e-mail, you need to answer it really fast. Just, that's not possible when you're asleep. And, that has happened to me 2-3 times. It seems, they stick only to US time.
Nevertheless, enjoy! :)
