Sharing a Notebook with another Joplin User?

is it possible to collaborate with other users of Joplin? Can I share Noteboods with Joplin-Users? I am used to work with Evernote where it is possible to share this way…
Thanks a lot for your answer!

I don’t think it’s possible to do it directly.

One way I can see to do it would be to use a separate joplinportable.exe in a separate folder with it’s own profile and notebooks. You would then have to come up with a way to sync it, a common network drive perhaps with a file system sync?

You would NOT be able to run both you r normal instance and the separate one at the same time.

Thanks a lot for your immediate reply!
