Authors merge several event dates in a run. The author creates one run per language.
The author can create runs as well on the course as in the Participant management of the course activation, but runs created in the Participant management of the course activation are only valid for the current course activation.
Without the right Create general runs in participant management the author creates only exclusive runs.
If an event date is in a run, the user can only registrates or deregistrates via the run.
Authors can also define a run as list of interested parties, this means the run is without event dates.
