How to facilitate meetings / events with participant registration, agenda and documents? How to manage meetings in Drupal? I would like to do the following:


Participants can register for an event or be added by the admin.
The meeting has an agenda, consisting of a number of agenda points.
Documents can be attached to the various agenda points.
Participant details, the agenda and documents are shown.
Record that the meeting is one in a series of meetings of the same group.


An example of what is needed is here, but the site is Joomla and it seems to be a custom module.
There are many options in Drupal allowing you to add registrations to content. So if you add a content type of 'meeting', you can add file fields, dates and an agenda text field. Add a taxonomy field for grouping by type.

Then with any of the registration modules you can register users. 


Entity Registration
Node registration
RNG (Drupal 8)


Basically it is not one module, but a combination of fields and modules to get the desired functionality.
