I signed up for accounts in Earnsurfer.com and Earnmailer.com last month because earnings from those two sites can be converted to load. But they can also be exchanged via Paypal when your earnings reach $100. Earnings from both sites can be seen if you log in on either accounts.
You can earn in Earnsurfer by installing a browser extension/add-on and once installed, ads will be displayed on the Earnsurfer bar and you'll earn if you click and view the ad. As with Earnmailer.com, you just have to embed an ad on the email signature so all outgoing emails will automatically display an Earnmailer.com ad. The ad contains a unique code so Earnmailer.com can track all ad clicks and impressions coming from a member's outgoing, forwarded and even re-forwarded emails.
I've never tried claiming load but some of my friends already did. They said it's very easy and fast to redeem. In a couple of minutes they already received it. I'm still piling up my earnings so I can get more load.
