Using Joplin Cloud you can share notebooks between users and collaborate on them - i.e. any participant can view or modify notes in the shared notebook.
Click on it, and it will display a new dialog where you can add any number of recipients. From this dialog you can also remove a recipient or unshare the whole notebook, in which case it will be removed from everybody's note collection, except yours.
Then, finally, once the invitation is accepted, Joplin will download all the shared notebooks and notes. A shared notebook is denoted by the usual Share icon. Now the invited user can read or modify the shared notes, add attachments, etc. and the changes will be visible to everyone with access to the notebook.
Currently they have full access to the data, including reading, writing and deleting notebooks or notes. In a future version, access control might be implemented. For example, to only give read-only access to the shared notebook.
* Plan a trip with friends or within a small organisation. For example, the notes could contain the maps, hotel and flight reservations, etc. or any document or note relevant to the trip. And all participants would have access to them.
* Work on a project with colleagues. Everybody can access various work-related documents, add to them, modify them, etc. That could serve as a knowledge base for a project.
* Another possible use, which has been requested many times, is to support multiple profiles. You could create a main profile that have access to all notes, and in there create a Work and Personal notebook. Then you would create a separate account for work. You can then share your Work notebook with that other account. That way the work account will only have access to the Work notebooks. You can use this technique in various ways to split your notebooks between multiple accounts and ensure strict separation between datasets.
