number of discussions to get 10$??

Well,I think nobody can tell you that.Because it depend on how high the quality of your responses.If you only say less words,you will need more number of responses,but if your responses are very high quality,you only need less responses to get 10 dollars.So I suggest you try to improve your response,don't care of the number of responses.

To be able to earn $10 in a month, I read in another discussion that you have to post about 35 times in a day.

You will earn 1cent for every discussion you will reply too. You can also earn 1cent by uploading image in the your interest. You can also earn when people reply to your discussiom, but for that we don't really know how mylot calculate it. So if you want to make 10$ just by reply to discussion, you most post a lot :P

I recently made $10 after about 560 posts. Most of these were replies to discussions. However, I have been told that it isn't that clear cut. You really have to do a lot of good discussions to reach ten dollars. It seems you get paid about 1-3 cents a discussion. I always figured on one per discussion and worked from there. But each reply and each discussion should be at least three or four lines each. More is better.

i find it hard to earn $10 a day. i only use internet part time and my earnings i very slow. i think if you spend more time here you can earn that much. and besides mylot site is not actually for earning big bucks but enjoying the company of others.
