What does the Star mean in MyLot?

It means your mylot reputation. It can either stay, increase or decrease when someone mark you + or -. I don't know if it has anything to with earnings but anyway if it goes down and you don't break the rules, don't lose sleep over it. Keep posting, the star will go back up in time.

it seems when people give us a + it affects our stars , so the more +'s we get the higher our stars , I like to give everyone who takes time to answer my discussions a + as I think it is a nice way to say thanks , well done you , xx
