I guess that would work for the time being but when I tried to sign up with them when they first launched they checked out my site and saw that I was using the Ebay Partner Network and said that I'm better off sticking with them direct as Driving Revenue takes a percentage of what I make from the Ebay ads. Ebay pays me direct and it's only their cut that's kept, not theirs + Driving Revenue.
From what I have seen on a forum that I have set up with viglink it is more like they give you 25%. On a few affiliate links where i know exactly what the product was and what the commission the site gives affiliates it shows me earning 25% of the commission. Unless they receive drastically lower commissions than if I would personally sign up with a site then the taking 25% isn't true.
I did add it to test but it doesn't rewrite the Ebay links. Amazon rewrites fine but Ebay doesn't get credited nor rewrites. I'm adding their specific code to the footer template and when I test with a link their site says that VigLink is installed on my site. My two clicks to an Amazon link shows in my dashboard but my 3 to Ebay links do not.
That being said, I would be willing to pay for a version of the modification above for Xenforo.
