So I have been a member of Crowdtap for a few months and was very discouraged at the fact that I was getting no where. It is a great site to earn some extra cash, if you can get a large following and have some people join. Well I had been at $2 for months until a nice lady told me a little tip. If you are needing some people to rate, you can always use a different browser to pick up the slack. It was almost overnight that I went from $2 all the way to $19.50. I highly recommend joining the program and using that little tip to help earn some extra money. While you obviously won't get rich, you can get a few bucks for gas!
