[OJS] Open access vs. Subscription

Hi everyone,

I’m still new to this and I can’t locate any documentation to clarify my issue. I’m running I’d like to make some articles totally open-access, no log-in required. For others, I want to require people to register/log-in, but I don’t want to set up a subscription because I don’t want them to have to pay anything.

Is this possible? If so, how?
