What does the STAR in your profile stands for???

By the way I also got few stars. Few days ago I got 5 stars and Now I have 4 stars. I think they give stars by looking how much you spend time on mylot on responding and posting discussion. Its been few days I havent got time to open Mylot, hence that may cause decrease in my stars.

This is your rank on mylot. You get them appeared next to your name when you reach 100 discussions. The number in the bracket next to your name is the accepted number discussions you post. It would decrease if you post response which would break the rules of mylot. and yeah if you will increase your ranking your payment would be more as compared to the one who are ranked below you. Just dont paste any website link until you reach 500 discussions. I hope this will help you out. Have a nice day
