In v3, I plan to make this hack only half dependant on uCS. You will be able to change your currency (the option to do this in this version is really just a "preview"), but for the moment, the 'uttpoints' is hardcoded, sorry

In v3 you can install another points hack (or write one), and have RPG work with this, and I see you have clicked install, so you will be notified over email when v3 is out
