Via a campus license, all teaching staff at Bielefeld University have access to a TaskCards license, which can be used to create an unlimited number of pinboards.
Newly created content is "private" and must first be set to "public". The public link can then be emailed or embedded on a web page. By default, no TaskCards access is required to access a pinboard content - all staff, people with link can view the content. Permissions for editing, must be changed separately on each respective pinboards.
