I suggest you read the Guidelines and other discussions because this type of discussion will be deleted and not earn you anything.

A star for any mylot user appears only when the person has reached above 100 post
and on every discussion people rate you by pressing the plus or negative sign of your comment or the discussion you started,the smallest rating is 1 i think.,the how many times you get rated by other users will determine your rating ..You can also point your cursor at the star and youll see the no./100 rating.try on mine,my got decreased after i did a discussion from 9 star to 7 star:( ..so star is something that you cant have always unless u are able to keep it up all the time.Also when you get as best response from the discussion board the rating also goes up.

Stars are the rating performance! you will get the star when you reach the 100th post! if you are more active and you post a good response you will get high star rating!
