Is it worth creating a token if my organisation only uses one course on MHPOD?

Yes, sharing a token can still provide a number of benefits. A token means you do not have to explain to your people how to find that one course. After adding your token they will see it in their library, before all the other MHPOD managed categories, branded according to your organisation. As a workforce manager, you get access to reports showing exactly who has completed that course.
