Hi Zerolu,
Siure, you will need to point your domains to ns1.trafficz.com and ns2.trafficz.com, then login to your trafficz account, (personally I would go to "old manager" its much easier) once you have clicked on that (link is about halfway down the left hand side of the page) then you will go into a much little white and orange screen.
Look for the link that says "import domains" click on that and you can then enter your list of domains there.
Let me know if you need any other help.
Kind Regards
Gary
