I am using OJS 3.1.2-4 with mulitple journals within one OJS installation. I have a user that is registered in one journal and would like to get him registered to another journal as well. I don’t find a way to do that. Neither user himself nor me as a journal manager. In OJS 2 there was an option ‘register existing user’ that I can not find it in the OJS 3. Please help.
