I would like to add people/entities to the contributor list, so they have an author box and a contributor page, without sending them an email. Some of them are ones I need locally (“Guest author”) and some are entities where there is not a clear address to send to (like a news service). And, the catch is that in order to be added, someone somewhere has to click the link in the email that is sent and set up a password, which in these cases is not possible.
Is there a way, then, to add someone or something as a contributor without sending an email?
