myCRED Simple Integration Addon is very easy to setup addon and bridge between myCRED and GD Rating System Pro plugins. Once activated, it will add new Points hook into the myCRED Hooks screen, looking like this:

myCRED Hooks for Content rating
myCRED Hooks for Content rating

Setup is very similar to all other myCRED hooks, and it will give points for the rating of the content (posts for all post types, default and custom), and for all rating methods. You just set the number of points to add, the limit for the points and log templates.
