Invitation workflow
Currently only the "core" forms are visible on the homepage (Harmonia+, Pandora, Pandora+). When a facilitator/administrator creates a group for a custom form and invite an user to submit assessments in this group there is no clear way for an user to do this...
So we should find a way in the interface to allow an user to
- create assessments for custom forms marked "public"
- submit those assessment in a group
