Imagine this
Campus Nursing Research Journal
Your school already has a WordPress site. Three faculty edit a student research journal. Today they use email: "Can you review this PDF?" Folders get lost. Nobody knows who claimed what.
With WJM they install the plugin once. A student opens nursing.example.edu/submit, fills the form, uploads the paper. An editor opens Journals → Inbox, claims it, sends a review invite, accepts it, and publishes. Readers see the paper on the journal page.
They never open Stripe. They never buy a DOI on day one. Email stops being the workflow.
