scheduling lunch

You can use advanced scheduling to create a number of calendar events and then include a number of users.  Create a new unlinked appointment and then select the Use Advanced Calendar check box.  Then go to the calendar tab and check off everyone that you want to be at that lunch.  Click on a new line to make another one for the next day and so on.

Chapter 2-202 in the Online videos is also about Advanced Scheduling.

In the Company Preferences, on the Calendar tab, you can set the studio hours.

Also in the Company Preferences on the Scheduling tab, there is a choice for how to handle conflicts.  I would recommend that you choose Allow after Prompting so a user is prompted if they try to schedule in a slot that already has lunch scheduled.

Finally, there is User Security in StudioPlus, but it needs to be turned on.  Once you have user security enabled, there is a security setting for Scheduling Permissions.  Be sure to read the warning box on this topic before enabling security.
