what is the meaning and what to do with STAR ......?

Star are just a indication of your quality of responses. It will vary as the user rate you postivie or negaitve. Just move you cursor over the star and you will see you mylot reputation. Ita 82/100 , a 9 star has a rating of 85+/100 and a 10 star 95 +/100 ...this pattern follows to other lower stars too. So its primary detemine the quality of your responses as decided by other users. It is also an overall indication towards you activities here. So if more people rate you positively more will be you reputation. But anyway it does not affect you earning directly. But everyone feel that a 10 star is better so would opt for him as friend. I think you have understood what I mean. Good Luck sone you will also be one with 10 ..!!!

Hi nothing to worry, its just ur scores and the rating from Mylot. Remember ur report card at school...its just like that. hehehehehe
