Just be aware that if you do buy points, they will not be available immediately. The site admin has to manually approve those transactions. I would recommend checking in the top left corner of Chat to be sure Zab is around before buying points if you are wanting to be sure you get them in a timely manner.

I recommend Crowdflower and Radio Loyalty as they are the most consistent about awarding points.

Use sandboxie if you are going to do downloads to protect your pc.
