we need to set up a website for a congress.
We need to have group registration, i.e. a group leader registering all group members with some user defined fields to gather specific information (i.e., celiac or other for foods and so on). The requirement is that the group leader can enter names and submit requests, but he/she can need later to add new people, edit details and/or cancel members of his/her group, and to have some report (member list, maybe export,...) directly in the front-end.
Can we achieve this using matukio?
