how to increase the earning in my lot ?and how to get a star?

There are a few ways to do this. 1) The more you participate, the more you earn. Though remember to make your posts quality, not just yes or no answers or one liners. 2) Posting pictures in discussions can help with your earnings. So the more pictures you add (though only one per post), the better, just be sure you have permission to use them, or better yet, only post pictures that you take yourself, to play it safe. And 3)referrals can help with your mylot earnings. The more referrals you have, the better, so long as they are actively participating on here. Otherwise they do no good. You will receive a star when you reach 100 posts. The people in the mylot community rate those of us on here, so depending on how they rate you will determine what star you will get. There is controversy on whether or not it affects one's earnings, though I know of at least one user that had such a low rating she didn't even have a star after she passed her 100th post and she stopped earning anything soon after she lost her star. Though it seems this isn't the case with anyone else that has any kind of star on here. Nothing really happens after you receive your star, though once you reach 200 posts you can use smiley's and other special codes on here. And when you reach 500 posts you can copy and paste as well as add photos to your responses, not just your discussions that you start. I'm pretty sure that's about it, though I might be forgetting to add something. I hope this helps!
