What do this mean?please tell me.

The 7 in your star is showing us you're reputation, from a scale of 100 on MyLot.com. This usually goes up when you get best responses, or when you get + rated! A fun thing to do is as well with this star, is keeping your mouse for a couple of seconds on it, and their will appear how much points you are rated on the scale of reputation of 100 points. In my head, I believe for example; Mine is 68/100.. I usually try to get it up by giving fast high quality answers, and having nice discussions with people! It's a fun kind of extra thing of Mylot.com

From what I understand, the seven in the start is your MyLot reputation. The way I saw someone else say it works is that other users vote on you or whatever. They said the "voting" is done using the boxes to the side of our messages. The ones with the "+", "-", and "!" symbols. If you hover your cursor over the star, you can see what your reputation is out of 100. As you can see, yours is higher than mine :P

my friend, that star above your pic means you've earned a mylot reputation from the rating that readers of your discussions gave you.(^_^)

well this is your mylot reputation.your rating will get increased or decreased by the number of rating your discussions and responses got.your mylot reputayion is out of 100 and your star rating will be based on what rating you got. i have also got 7 as my first rating recently..
