If I'm on the Specialist plan, does the person I invite have to also have a Novelcrafter account?

In order to invite someone to your novel or series, they need to have an account. Depending on the role you want to invite them as, depends on the type of account they need:

1. Editor: Your collaborators will need to have a paid plan (even scribe) if they want to add or edit data. In the invited novel, they will have the same privileges as those with an artisan plan (i.e. they can use AI within the shared novels).
2. Viewer: If they only need to view data, a free account is sufficient.
