Quote From rewt:
Is there any point in signing up for ORCID? I see the point of it it being an independent way to document all your publications, jobs and grants etc. But is it worth a PhD student signing up for it or are there any disadvantages to having one?
No disadvantage. No one looks at it, so no real value in keeping it updated.
Value is that some journals/ funders require you to have an ORCID ID.
