I agree with just about everything here.
I want to expound on the advice about using your website.
A lot of people who are new to website building (html) will assume that you only get one page and so you have to make the best of it by hitting home with your message (to do GDI) on the front page.
NO NO NO!
You can certainly have a page on your site that tells all about the GDI opportunity and links into the presentation. In fact, I would highly enourage you to do it. But don't make it the main page.
Your main page should be something of a general interest nature. What kinds of things do you like to do? Do you like to fish? Do you like to collect things like coins, stamps, coke memorabilia? Those are things that you can build a great general interest site on, that will draw people to you like flies. Then include a link on your pages to your GDI information.
Why? It's simple. Nobody goes to google and looks for network marketing business. Or, if they do, they already know about this one! But they do look for other stuff.
I also agree on the subject of cost. Is this the most cost effective web hosting? Nope. That's not what sold me on the idea. I already have a company name that, unfortunately, was not as unique as I thought it was. So the .com, .net, and .org versions of it were already taken! But the .ws wasn't! To me, it was a simple way to get an easy to remember name and I think that is the best approach to sell it by.
Of course, it doesn't hurt that I can automatically make money with it, and add a new profit center to my existing web business.
