VigLink is great for monetizing your forum or blog for mobile viewers. It is compatible with both ForumRunner and Tapatalk and I believe you can install it for normal browsers as well. Basically it uses many affiliate networks and you only have to go to one spot to monetize all of them. You can also set it to write over anyone else's referral links so that no one else can monetize your site except you. I have heard many people say they make more from VigLink on their forum than they do from AdSense.
