Can I create new points rules in EasySocial

Where are the .points files in EasySocial?

Is it possible to write a new points rule based on an EasySocial action? I'd like a rule that assigns points when a user comments on a post that is on a Page. I looked at the developer documentation, but that looks like it's instructions on creating rules for a custom app or 3rd party extension to integrate with ES. Is it possible to extend the core EasySocial rules? Where do you come up with the commands?

Also, it's possible to put a max limit on points for a rule, but it is possible to set a daily or weekly limit?

Thanks, Karen
