Your Locations are in the top right corner under your Company name:
Publish a Location
You will need to make sure the Location is published before people can enroll. To do this, click on the cog icon and then the eye icon. If the eye is open, the Location is published.
Unpublish a Location
To unpublish a Location, click the eye icon again. If the eye is crossed out, it means the Location is UNpublished.
