I should mention, Rockstar creates a Rockstar folder in My Documents. I am not sure how that would work being in a different Windows user account. You would probably have to tweak a registry key for that user to point the user to the admins Rockstar documents folder, although again, I am not sure how that would work. I am not exactly sure about this with Rockstar, but there are reg tweaks for a lot of aspects of Rockstar Games that don’t break the TOS.
Rockstar forums would be your best bet. If you’re playing as the same user then I can’t imagine you’d be doing anything wrong.

Not sure what’s official with Rockstar forums anymore, there seems to be a few. I keep to myself so I don’t use them.
