CAPTCHA 4WP – Antispam CAPTCHA solution for WordPress


For the past week, my site has been inundated with fake account registrations. Since adding this plugin yesterday there haven't been any new ones. I'm hopeful that it won't cause any problems for students signing up for my courses.


Yay no fake registrations today!


5 stars, no notes - MU/multisite support greatly appreciated


Perfect for me and MU support
