I think a lot of them have high volumns of buyers and sellers already, so they tap into their own warm market and use autoresponders, lead capture pages and other things to automate the process. Then send out an e-mail to their huge contact lists and get lots of signups. We are just starting out and have few contacts compared to them, but we can start now building them up by just treating others as we want to be treated and being a friend who is willing to help others.
