Our company doesn't have projects that need to be hidden from users, however unless we assign those users to a project they can not see it.
Example
The finance people need to see how far the project is progressing, the customer support need to see what the status is for all customers etc... but these individuals won't be doing the work and shouldn't be a part of the resourcing or billing.

How can I set this up without giving everyone admin rights ... which is a firm no from my company.
