whats with the star on top of the perons user name?

That is the rating you get by other MyLotters I think. If you get a lot of minus ratings your number is lowered. You need to reach at least 100 post before getting a star. There is a site where you can get all this information. I just typed in "Star rating" and it took me to post where I could find where to go to get my information. Any time you want to know what people are saying about a certain subject just type that topic into the Search bar and it will take you to that topic.
