What is the difference between a Main Contact and Project Contact within the SparkSafe system?

There are two contact types within the SparkSafe system.

 

Main Contacts:  There must always be one Main Contact assigned to a company, this will default to the person who initially registers the company.  You cannot have multiple Main Contacts.

Project Contacts:  There must always be at least one Project Contact assigned, this will default to the person who registers the company.  There is no limit on the number of Project Contacts.  The Project Contact will be the person who appears on the project view and project report.
