At our school, we have 4 calendars that need to be published/accessible for faculty/staff and parents/students to see: 1. Faculty/Staff calendar - events specific for our school (with dates, times, locations). Only faculty and staff are able to see this calendar. Password protected. The registrar maintains this calendar. 2. Parents/Students calendar - events specific for our school (with dates, times *but* no locations). Parents and students are able to see this calendar. (If faculty/staff want to see it, they can.) We'd like this one to be password protected. The registrar maintains this calendar. 3. Principal's Office calendar - a calendar shared between the Principal and her assistant. Password protected. Only the principal and her assistant maintain this calendar. 4. Room scheduling - rooms at our school are rented out after-school hours. Faculty and staff should be able to see this calendar. Password protected. The director's assistant maintains this calendar. Is there a way that we can maintain these 4 calendars under one account (I'd make the principal in charge of this Publisher (Master) account), with 3 additional subscribers (Editors) to this account (for $30/month each), and have each of those subscribers (the registrar, principal's assistant, and director's assistant) only be able to see those calendars that they have to maintain (not see the other ones)?

Is there a limit to the number of calendars that can be created in Trumba?
