Only PM/Admin users can add references to projects.
1. The materials are forwarded to the PM who uploads them - this is not real-time
2. The Linguist is changed to a PM temporarily, with the necessary access restrictions (e. g. no access to other projects) - this is not reliable
3. Sharing knowledge via a cloud service such as GDrive and adding only that link as a reference in the project - this involves an external service with its security and confidentiality risks
Linguist users can upload or add references to projects
Linguists should be able to support each others' work in real time.
