WangGuard is fully compatible with Standard WordPress (non-multisite), WordPress MU, WordPress Multisite and BuddyPress (multisite and non-multisite).

If you have signup enabled on your Standard WordPress, WordPress MU, WordPress Multisite or BuddyPress, this is the plugin you were waiting for. There is nothing like it, is a next generation plugin associated a web service and a new concept of active protection from Sploggers, spam users or unwanted users. This is just the beginning.
