Three groups, depending on who you are: someone learning on their own, someone deciding whether to bring an institution across, or someone working out what it costs. Each group is also answered on the page it belongs to.
Signing up as yourself, with no institution behind you. See the home page.
Bringing a department, a faculty or an institution onto the platform. See for schools.
What the plans cover, and what is never metered. See pricing.
Say what you are trying to do and who you are asking for. A learner, a department head and a journalist need different people, so the contact page routes you to the right one rather than to a shared inbox.
