1) The problem → I can use Memberstack on multiple websites / domains, but I don't want members to have to log in every time they switch websites. A portion of my content lives on another website/subdomain/CMS.
2) Why is this important → My CMS isn't on my main marketing site (where people log in) and I really don't want to give up my CMS. It's core to my value prop.
3) What's your plan B → Leave half of my content "unlocked" or move all of my content into a single domain.
