what is the that rating put in ( ) next to our username

this is what i understood from mylot guidelines. increase your reputation is by contributing quality topics, responses and comments and avoid breaking mylot rules! users with a user rating of less than 100 will not yet have myLot reputation myLot reputation is determined by the myLot community,not user It doesn’t mean that 8 stars means “good user” and 5 stars means “bad user” only indicate how active user are

The rating that is put in the brackets after our user name isn't a rating actually at all. The number that is in the brackets is actually the amount of responses and discussions that you have been involved in!
