Thanks for that - that is what we usually do.
The reason for my question was :
The Sony & Microsoft RCs have hundreds of tests that must be completed to meet certification.
These can get updated every few months.
It would be a huge task to create and manage these Test Suites.
Anyone who is developing Microsoft Xbox One or Sony PlayStation 4 games would have to individually copy these tests from a document in to TestRail Test Suites and then have to maintain them
However - if some TestRail user has already entered these Test Cases / Test Suites...
can these Test Suites be shared to other TestRail users (like a Repository)?
Can they be maintained by many users - like a wiki page?
And when it comes to creating a Test Run, we can grab the suites we need from this central Repository.
I am likely going to start creating these Test Suites myself.
But how would I share these with TestRail users who are developing Microsoft or Sony products?
