Hello
ACL works as in Joomla (read Joomla docs) but we have more ACL options

-- Use ACL for controling category assignment ("create" privelege in component/category permissions) and also ACL for controling which
types can be created by the user ("Create Items" ACL privelege in type configuration)
or you can use a submit menu item override to force a specific category and/or specific content type, thus ignoring ACL

-- you can do "receive notification" in component/type configuration, and also do "edit" via ACL edit privelege in component/categories, but the "only set to in progress" is not possible, you will either give user
edit state or not give him
edit state

- see answer above (for 2) maybe permitting specific states will be configurable in future version, now this is not available
amaida wrote: 4. user "d" set the item to published, and all users of the community will be notified of the new item.
- see answer above
amaida wrote: The main feature I am looking is that user "a" should create only items in specific category and using specific "content type". I tried to do this creating a group "creatore a" with specific permissions , but without successs.
-- see answer for 1, this is possible for both category and for (content) type
