I would like to add few more earning methods from my end:

1. Services:

In this section, members post bounty options for those who can help them either in programming or any other task (eg: a signup on a website, forum posts and so on). This job can get a person earning irrespective of his account rank.

2. Digital Goods/Goods:

Here the members can sell their digital goods like gift cards or physical goods and earn BTC. A simple a safe method.

Also in the Faucets section, kindly write that it's a low earning method. Also if possible, rank the options as per the earning capability. I feel Signature Campaigns pay higher than the other options but that's my POV.
