I am developing a membership site currently with a friend. We are fairly certain that we can get 5000 members who should be fairly active within a year. Beyond using a subscription model, what other ways would be good to moneterize it? I was thinking about using some kind of PPA program. Unfortunately I do not have a lot of knowledge about using them. Basically, find a way to automate the process so that it would be as simple as possible for them to use. Anyway thank you for any responses, good, bad or indifferent.
