When creating New Users you can set their default Page Layout, Time Zone and Country. To set new user defaults click the Top Menu button and choose Users.
Click the More drop down and select New User Defaults.
Depending on the new users you are creating, you may want them to all have the same page layout. For example, if you are creating new staff users that are similar to other users you have already created, you may want to copy the their page layout. In this case, click Copy and choose the user whose page layout you want to copy.
