I created a user on my blog called "Other Author", as well as a custom field by the same name. If that user is selected as the author of a post, my single.php file is instructed to show the content in the Other Author custom field instead of "Other Author."
First, is there a better way to credit a post to an author other than those set up as users on my blog than the way I'm currently doing it?
Second, "Other Author" is still what comes through in the RSS as the creator of the post. How can I filter the RSS to use the custom field instead? I've tried looking through SimplePie some, but I can't figure out what I'd filter.
