No reward points..It represents the number of posts that you make and in some cases you get extra points as shown in the Legend shown over to the right here. Just make a post and you will see that your number will be increased by one.
Ok....so what exactly are these points for? Is it mainly used as a way for the site to track who is on here the most, chatting up the blogs and so on? Just curious as to why even have the points if it doesn't lead to anything.
