can you rate discusions

Yes, you can rate any discussion and also the responses to any discussion whether you have participated or not. You will see the + and - options to the right of every post. Most people only bother with the discussions that they respond to and the responses to their own discussions, although it is personal choice. The rating should change or affect the star rating of members. It should also play some part in the overall earnings, although I am unsure as to how this works.
