If you get leads to use either from GDI or other sources you can add them into the invite system and check your stats in the members area If you're a premium member you can load leads automatically. If you buy leads from GDI they'll load them for you. I think getting leads if you can and using them to promote GDI is one of the easiest ways to build your biz online. You can call them or just send an invite to see if potential clients are interested. Check out my Tunes Net blog for some free leads sources
