There are hundreds of plugins for WordPress that customizes or replaces the WordPress registration mechanism. This means that this hook cannot be guaranteed to work with all of these plugins!

The hook uses the user_register action hook to “detect” a new registration. If a plugin does not trigger this action hook, no points will be paid out.

The setup for this hook is very straight forward. You only need to provide the amount of points you want to give (or take) to a user when they register and the log entry template to use.
