There are 3 videos on your members area home page. The first thing you should after you register for the team site is watch those 3 videos. They show you how to setup your links so they are coded to you as well as how to use the rest of the resources on our team site.
Specifically, video 2 will show you where to go to add your 4 Corners username. You only want to enter your 4 Corners username in the box. Not a full url and no extra spaces or symbols. Once you've done that, go to the Landing Pages tab and click on one of the links there to test your funnel all the way through the process.
Do not send your links out until you have set them up and tested them.
