I'm doing a website for a local club and to make the site special I recommended adding social network plugin like buddypress to add extra functionality. I got to thinking about the possibility of having people that visit the club joint the network in the process I'll be creating a "list" for the club owner. Does anyone have any ideas of how to make money off such a list? It would be a list of night club patraints. How would u make money from such a list?
