How to link events with author's datas ?

Hi everyone,

I need to create a website where some non profit organisations will have to add there events in their own calendars. Each one will have his calendar, no problem there.

Each association needs to present herself so I can create a page for each one and limit authorizations to her own page, no problem again.

The problem is when someone reads an event (in event reader module) I need :
- he can clic to go to the corresponding presentation page ;
- or the presentation informations are displayed beside the event datas.

In some cms like WordPress, it sounds as simple as automatically displaying author/user datas in a page and some plugins let add fields as needed.
In Contao 3.2, I only find the same for members but not for users.

What could be simplest solution as we'll have to add 30 to 100 associations (and so calendars, presentations…)

Thans for your help.
