How can I purge old user display names?

  • My WordPress site is used to support I class that I teach. Every semester I purge all the personal information in the User’s profiles, and then have the next batch of students enter their personal information in their Profile on the first day of the course.

    This works well, but the drop-down menu for the display name contains all the names from previous students whose other personal information has since been deleted.

    Is there a way to purge all of these old names? I can’t find anything in the mysql tables – but I may have been looking in the wrong place!

  • you probably have to write your own sql query or you can go to the wp-admin >> users and checkmark the ones you want deleted then press the radi button called “Delete checked users” then the submit button

    it sounds like you’re re-using actual users… instead of allowing them to register themselves, and then deleting the old registrations (or not) at the end of the semester.

    There’s no reason to be re-using logins.
