Managers can create edit and delete fields and edit layouts in ACT!
That isn't good. I suggest that access to Define Fields in ACT! and Design Layouts should be included as a selectable permission only, which by default would not be granted. I see manager users as being able to manage access control and change record manager etc but giving the ability to change a schema is far too liberal and dangerous...people fiddle and the bigger the site the more the impact. If the site is also an 'attachment challenged' sync site the trouble is magnified.
