Context: When we insert content for clients on full-service projects, sometimes we leave the original author. This author is usually from my shop and has admin-level permissions. When we turn the site over to clients, many times they can't override an admin due to their own (appropriate) permissions.
Question: Is there a way to batch-change all authors to either another author or
null? Forethought is obviously the best thing in this case, but it's a pain to go into each entry and remove/change authors, and I'm lazy. I wasn't able to find a workaround or plugin. This question shows what to do in the database, but I'm wondering about the CP.
