I'm muchcat, and I'm not really "new" but just getting around to introducing myself. I started sweeping back in October and got really devoted to it for a couple of months. I got a couple of wins; an iPod, a bottle of body lotion, but then I decided to get all "good" and started going to the gym in the morning instead of sweeping. I abandoned the sweeps for several months, and then lo and behold I got a winning notice; a voicemail on my cell phone said I had won a cruise! 
I thought yeah, right. But when I got home, the same people had emailed me as well! When the cruise turned out to be real, I came back to sweeping (I had long since abandoned the gym). The gym just isn't as -ahem- rewarding as sweeps.
Since I came back, I've won a monogrammed tote, a Publix gift card, a $50 Amazon gift card, and about a million bags of Flat Earth Chips. I have a bunch of recently expired sweeps under my belt and I'm just waiting to hear I've won!
Anyway, GLTA !
