[x] How do collaborations work?

An artist has recorded with a band already in the dB. This artist has only ever recorded with another act which cannot be linked into the dB, albeit that this was part of a collaboration too. Can these be submitted to form links?

??????????

I don't think collaborations count as shared membership.

PK is correct.

There is no sharing of members. If one co-collaborator cannot otherwise connect to the family tree, that half of the collaboration is ignored. If both collaborators are in the database already, the release will appear twice in the family tree, once for each co-collaborator.
