Repository Stack users

[Jonny5]

Have a look at this thread from last year.

Repository stack - multiple users

I see that the Repository stack can have two users - for example an admin and a user. Is it possible to share the user id among several different people so they can all access the files and folders in the repository? And if so, what happens if two users log in at the same time and starting moving, editing, uploading and downloading stuff? Thanks Rob
