I have several large forums ranging from porn to a kids site (not porn haha) And I just now utilized my members list. I now send out a mass email to them once a month (I dont want to harrass my users) with offers and discounts from other affiliates so on one thing my hotfile affiliate went from me only having 100 affiliates under me to now having 800!!! That is a big difference in just one day! So if you have a forum take advantage of it. Dont be like me and wait for so long.. haha Hope this helps someone!
