I've been customizing around user access rights and found it to be very confusing.
Should I assigned user to some default groups created by OpenERP and then create my new group for further access rights ? Or should I not assigned user to some default groups but instead use my new group right away ?
If my above questions are confusing, then change my question to : :
If I have many users and they must have a complicate access rights, what are your recommendation on setting their access rights ?
