How does one set one's account to be a subscription service? Can this only be done on the whole account (blanket) or can one set certain posts with certain content to be for subscribers? Is there a selective touch or is it all or nothing? I have clicked on profile page expecting to see a cog wheel or "settings" or "account preferences" or something but alas I cannot. It also lets me follow myself? I know I should perhaps not have admitted to having done that.... as Phil Collins famously sang "I will follow you if you follow me"
