Congrats for signing up to become a Buzz Member. So your aim is to get IGG points, aka Item Mall points?
First of all once you become a Buzz Member you will be able to view your IGG banners and links.
Here is a link which may answer your questions:

Link to your Promotional Banners (click the drop-down for ones for other IGG games):

Link to your Promotional Links:

Your Banners and Links are what you will be using to promote the game. You copy and past them onto other websites for others to see. When people click on them on those other websites they will be directed to the IGG game the link is for. For example if you put a WLO banner on your Myspace and someone there clicks it, they will be lead to WLO. If they sign up they will be marked as being Promoted by you.
In order to get something out of it the people you promote must buy and use Item mall points. When they do this you get some Buzz Credits. You can check how much Credits you have by checking out the Buzz Zone when you are logged in. These Buzz Credits can be exchanged into Credits for the Credit Mall, real money, or Item Mall Points.
