has now been added

There is a new addon available for the plugin:

Linkwise is the first and largest Affiliate Network in Greece. Launched in 2008, it has since been at the forefront of the Affiliate Marketing sector and works with the largest brands in the market. In 2012, Linkwise launched its own custom-built affiliate platform (the first in the market) which brings its services and -as a result- Affiliate Marketing in Greece at a whole new level.
