This will work for any advertising purpous.What I did was created a ning site that is basically just the home page.All I added to it was a text box.Then I typed up a story of what my opportunity is,and placed my affiliate links in the story. Now all I do is direct people to the "story about what I do",from twitter, facebook,myspace,the .ning networks,Iether by posting a coment on thier profile, or joing groups and starting descusions,or posting links on twitter.The "story" does the work, on a page where nothing else distracts away from it.
If you want to look at it so you can copy the Idea,using your own opportunity, you can view it at
