Whats mean of of Star in Mylot.com for every users ?

pls see more details abt this Mylot user reputation system at a discussion started by Mylot administrating staff here : http://www.mylot.com/w/discussions/573319.aspx

it is based on your rating I believe.

Users with a user rating of less than 100 will not yet have myLot reputation calculated, and will therefore have no star next to their name. myLot reputation updates once per day, so most users should see their reputation appear shortly after reaching a user rating of 100. Remember, myLot reputation is determined by the myLot community, and it is cumulative for all user contributions. Therefore, myLot reputation can fluctuate even without a user participating on any given day. In addition, you shouldn’t think of a particular myLot reputation level as necessarily being “good” or “bad”. It just means that a user with a reputation of 8 is generally more highly thought of by the myLot community than a user with a reputation of 5, and so on and so forth. It doesn’t mean that 8 stars means “good user” and 5 stars means “bad user”. Both are valuable members of the myLot community. As you might have guessed, the best way to increase your reputation is by contributing quality topics, responses and comments and avoid posting low-quality content or items that violate the myLot community guidelines. HOPE ITS HELP

The star number signifies your rating by other users.

it's your rating, the more + ratings and best responses you have the higher is your star and it raises also a bit yor earnings. that's what I know
