GCstar forums - multi-user capatibilities?

Dear GCstar users,

I am new to GCstar; in fact I have not yet started using it.
Before diving in deeper, I would like to know a few things about GCstar's multi-user capacity (or lack thereof).

I am searching for a solution for managing my book collection.
However, the collection is not entirely "personal"; it belongs to my family and friends, too.

Therefore, there are more that one users who would need to use this software.

What are GCStar's multi-user capacities?

Can it store who edited which record?
Can it store who has and who has not read a given book?
Can it store the notes of different users about the same book?

Thank you for your help:
