Hello,
sorry for the wait, I didn’t get the notification e-mail for your question.
You can restrict any non-admin user that can edit pages: Editors, Authors, or any additional role that you might have created manually. Administrators and users without the ‘edit_pages’ capability won’t show up in the Page Whitelists editor, so that might be your problem.
Users can be assigned to whitelist when you create/edit the whitelist (Options — Page Whitelists), or by editing the user (Users — Edit User). Note: make sure you upgrade to version 3.0.2 of the plugin, there was a bug that caused some problems with the Edit User form.
Pages can be added to a whitelist from the whitelist editor, or directly from page editor (the metabox might be hidden by default – display it from the ‘Screen Options’ drawer in upper right corner).
I hope this is enough info to get you started, but ask if you can’t figure anything else out!
