There are many, many resources you can/should use to be successful in building your teams. Use various online classified ad services, bulletin boards, and forums--if they allow affiliate program links, of course--to boost traffic to all your gateway links. Use fliers and direct promotions to make real-world connections. Because I publish comics as a hobby, I advertise on the back pages of those to spread the word. There are no limits to the amount of different ways to build teams. Use them.
