Hello. Thanks for your suggestion of register plus redux. I gave it a try, but unfortunately the plug-in does not seem to block unapproved visitors from logging into the site. You are not able to enter any extra registration form fields on the plug-in, without those not being recognized on the classipress registration page. And when you remove the extra fields and check the plug-in boxes that you want to verify all visitors, visitors are still able to log into the site without approval. I wonder if anyone has any other suggestions. Thank you.
