I just upload my blog with wordpress in my host. But I want to make some posts restricted to only those who are logged in and in some cases, the ones who pay for some "super premium" content. I have no idea if there's a plugin to do that or maybe another way to do it, but I really need it. It could be perfect to sign up by email, or social media and get those emails later to add them to a newsletter. Thank you so much for your help and guidance!
