Hi @bozana
How about having an extra setting in the Crossref plugin that would enable users to register DOIs automatically when a new issue is published?
We are using the automatic deposits, but the problem is that there is always a delay in the registration. So when the journals for example tweet about their new issues and articles and use DOIs, they are not working and crossref sends us error reports.
I have instructed the journals to register DOIs manually, but I think that it would be fairly easy to just hook the registration to the issue publishing action?
