How many sites would you say you run that require a subscription to use? Like a paid subscription that users must pay in order to use or access the site. I've talked about it before here, but I was curious if anyone has multiple sites that require the users to have a paid subscription in order to access it. Does anyone have any sites like that? I had one site in the past that people could sub to a certain area, but I haven't done it in a while. What about you?
