HELP!!! how to ues mylot?

First thing you want to do is read the guidelines and the FAQ, located at the bottom of the screen. Those two alone will tell you just about everything you need to know to post with success. If you don't read them, chances are your going to end up losing your posts/points due to violations.

You already have started to use it. It is mostly about opening discussions like you did already or answering discussions which you have answers about it. And if you want to earn more in this site you better have some referrals because you earn money from their posts too. And also uploading pictures is another way to earn credits. Good luck and let us know if you have further questions.

all you got to do is join in the discussions and start a new discussion and answer every comments and surely you will enjoy it and meet new friends here.

just answer some questions and responce to any of the topic..
