Don't pass up some of the tools GDI gives you in your own back office.  I'm using the "Advanced Users Nameservers" option.  With this I am able to use my "GDI" recruiting web site and keep the dot ws tag on the end.  This always makes you look more professional than if you an affiliate dot com site with along affiliate ID tagged onto the end.
   
I have found that many of us are looking for a way to promote GDI with a system that can be easily plugged into.  The system I use gives me all the tools, and training I need for free.  There are actually 20 plus step by step videos to follow.
