Allow user to mark entry as favorite, starred, or saved for later We're building a site with a recipes catalog and we'd like to allow logged in users to "star" an entry/recipe and then be able to view a list of their "starred" or "favorited" entries. Any suggestions on how to go about this?
This definitely sounds like plugin territory. I'd recommend Curate, by Lori Goldberg.
