can you tell me the techinique to earn money by filling registration form online

It is strange to be paid for filling up registration forms. Do be careful that you are not giving away any important information.

There are alot of those that actually requireyou to purchase or sign up for other things,so read them carefully some will take your information and use it for bad things if you are not careful.There are many sites out there that do pay you for filling out surveys and sometimes it takes a while to get paid,so be patient and good luck. Have a nice day.
