I'm looking to start a website in which people register to receive updates on certain event information. I then allow events that are looking for people to attend to post their event information on my site. In return I send the registered users an email about the event. Users see the link, go to the event's site, and register. I would get a commission off the registration fee. What is the best way to set up my site? Should I become a publisher at say Commission Junction. Can I somehow automate the process of registering, so that when an advertiser signs up to advertise on my site, they are automatically registerd with commission junction? I don't know where to start with my idea. Thanks for your help.
