I'm testing and discovering Q&A with the project to use it as our question-answer system in a library. In a first approach, we do not intend to ask registration to our audience. On the contrary, we would like to reserve the registration to the team responsible for answering (adminstrator and responsibles by category).
I could see that the registration form url is available only when connected as a basis user. Is there a way to make it work only as administrator and that would not imply a heavy code modification?
