[LON-CAPA-dev] A line from the guts manual about roles

[Jeremy Bowers]

"When a user first logs in, their role is the 'common' role, which means 
that they have the sum of all of their privileges. During a session it 
might become necessary to choose a particular role, which as a 
consequence also limits the user to only the privileges in that 
particular role."

Is this still true? It doesn't make much sense to me as written; why 
would anyone want to limit their privileges, and why would "limiting" 
privileges be necessary to do something?

I don't know what this was getting at. It came from SessionOn1.html, 
near the end.
