how do we earn here i mean how much for every discussion o coment or a repley

There is no exact amount you get. You get paid for quality rather than quantity. So always focus that while giving response its in detail. I guess you are new here, it would be nice if you go through the terms and conditions of the mylot as anyone fond breaching them will be suspended. Visit these pages you will get a clear idea about mylot. http://www.mylot.com/o/faq/faq6.aspx http://www.mylot.com/o/guidelines.aspx Best Luck.
