how many comment or discussion for a doller???

MyLot doesn't work like that. It is not a 'paid-to-post' site which pays per discussion, response or comment. You are paid according to your activity or participation, how much you interact with others and how much they interact with you. You can post as many discussions as you like but unless people respond to them and you comment on their responses it is NOT a discussion and you will earn hardly anything. MyLot is a social site and you are paid for being sociable. You can even earn something if you don't post any discussions at all but only respond to, comment in and like other people's discussions. Of course, when you start a discussion, get responses and interact with those responses, you will begin to earn more. Read the Guidelines and the Earnings Program FAQs for more information, You will find them under "Help" next to your avatar and username at the top left of any page. You may also find my Guide and (unofficial) FAQs useful:

If it's the same as before then there's no fixed price on the comments, post, and other activities. It would depend on one's participation in general. Anyway, many people already earned money and enjoyed the site before. I'm glad it's back.

There is no fixed exchange amount of word per dollar or discussion per dollar. That is why we all encourage you to have fun and learn and talk to others a lot.

I really don't know, as I just keep interacting with others, and starting a few of my own discussions. I find it better not to pay attention to my earnings. I come in here to have fun and that I do. As long as I interact, I will earn.

I cannot tell. There is not a fixed price per post here. Your earnings rely on quality and interaction. The response is already in the earning FAQ. You should read it.

well I am new here as well so I do not know the answer for this either
