On my Trello board: STRM044-SPRMU-2122 (Cohort 23) - Business Research Project (MIU) I seek to invite students that I encourage to sign up to trello.com first. After students sign up to Trello I share the invitation link with them. However, students cannot join and receive a failure message. I do have 629 guests, so at some point it has worked. When I seek to manually add a guest, also that is not permitted, as it says that I need to add that person as a workspace member. I only want to add that person to the specific board but not to the workspace. Kindly advise.
