I am searching for a way to let people sign up for one or many events, specifying a number of participants for each event instead of a simple yes/no.
Essentially for me this means a dropdown of e. g. 0..9 Persons per event.
Summary should show total number of persons per event. People should be allowed to modify their entries.
Bonus points for optionally pre-filling the rows of the matrix with members of a configurable user group, as well as allowing (potentially other) user group members to change all entries to track participant responses "on behalf", i. e. not directly entered in the wiki, but e. g. via phone or email.
Three events (Event A, Event B, Event C), three persons (Person 1, Person 2, Person 3)
Person 1 attends Event A with 2 participants, Event B with 0 and Event C with 1
Person 2 attends Event A with 1 participants, Event B with 1 and Event C with 4
Person 2 attends Event A with 0 participants, Event B with 0 and Event C with 0
Total for Event A is 3, Event B is 1, Event C is 5
