Courses or trainings often have a registration deadline by which the list of participants must be known in order to prepare documents (e.g. certificates or diplomas). Previously, this planning security did not exist, as participants could change their own feedback up to the start of the date. With the new function, a registration deadline can be set for one-off events, which is independent of the start of the actual event. A re-registration or change of the re-registration is no longer possible after this registration deadline.
