We have an upcoming project coming up which will have two sides, let's call one the marketing site, and the other is an app.
The basic idea is the marketing site will sell access to the app, so the user will sign up through the marketing site to have access to the app.
So basically we need to be able to share members and only the members between both sites. Is MSM suitable for this?
Technically, it could be done through a single site but I don't want to be mixing up the channels and other data between the marketing site and the app.
