how do you get rated on my lot?

You will get your star after you have reched 100 posts :) The color of the star corresponds with the number rating. The highest rating you can get is 10, lowest is 1. You get these ratings by earning best responses from responding to others discussions and helping them with any problems they have. And you can also get higher ratings when people rate your discussions and responses with +'s instead of -'s. You can rate others with +'s and -'s using the symbols at the right of all the posts.
