Another easy way to get points - Crowd Flower. You only need to complete the tasks they ask. There are currently tasks for 75 pts a piece and all you have to do is give feedback from Google search results. It takes about 10 minutes and you can do it twice for 150 pts. That buys you in to a Carbon freeroll. I hit the mother load the other day classifying wikipedia contributors. It was 60 pts a page and I filled out about 10 pages worth in about 20 minutes.
