How to increase my star rating?

you can't yourself change the star rating. i think you are just at 153 posts. try to post as much as you can .also post quality discussion and not so small posts. people will rate you and it can increase then.

you already done the right thing in submitting your response in here. your response seems having quality in my viewing . another thing that you should do that you should add more friend in your friend list. i think rating star also related with how famous you are in mylot world. when you have so many friends in your friend list, you would able to get known by your friends when you response their discussion and it also made your discussions would have good response in many. i hope its help you. good luck for you

You just have to give the expected answer to discussions, even if it is one line long. Or in other words, the author of the topic has to like your answer, or the other participants......so much that they will rate you +. Just to give you a hint...You won't get much rating from a single response posted to a discussion. The best way to boost your star is to start a popular topic, in which more people will rate your topic, rather than one reply. GOod luck!
