Good morning. If many people work in the process of verification and selection of items, what is the proper way to record the list csv without the following problems occur: 1) Repeat entries (Someone reviewed the same article because he did not know that was already in the list) 2) Create a shared list and easy to edit (We're talking about a list that may be so large that it is impossible to edit) Thank you very much for your help User:Wilfredor
