New mylot...got a lot of new features..liked the friend feature a lot...and also all discussions are well organised..only problem is its slow, and yes i would like to get rid of that 'preview discussion' button!
The new myLot is much more organized. You can see the discussions you started, the ones you answered, your best responses. I only now learn what were some of my best answers.
I also like that you can post your favourite images.
