Hello,

What you can do is to instead of adding points for user when they post a new question, do it in a reverse manner. In other words, their points would be negative when they post a new question.

Here's how your workflow should be:

1. New user registers on the site (+20 points) [Uses EasySocial to achieve this]
2. New discussion posted on the site (-5 points) [Uses EasySocial to achieve this]
3. As for buying points, we don't have any methods for user to buy points yet at this point of time.
