PFL.me is free to join service, right now very similar to AdFly (many improvements planned). PFL stands for: Get Paid For Your Links.
It caters to advertisers as well as those that want to earn money linking to any web page they like.
The idea for this came from creating a service similar to Adfly, but that actually provide great value to the advertiser, specially in the Internet Marketing or Income Opportunity niches.
Check it out at PFL.me, it is currently in beta state!
