All we know that since the world lives this economic crisis thousands on people they have left to look for new sources of income. Some look for a second use, others invest their savings to raise businesses or of realising investments. Nevertheless, everybody does not have money in the pockets to have the initial money. Then, how it is possible to be made to make extra money without needing investing the little money with which it counts? One of the most recent forms and than is growing quickly in the opinion of the public is to answer remunerated surveys online. When one register in a site of remunerated surveys, the poll sends a form that must complete with its personal data, a user name, a password and a post-office box to him to which to send the remunerated surveys to him. By comfort, it agrees to him that these three are equal in all the sites to which register, and exclusive rights of the surveys. Of this form it will not have problems of confusions or forgetfulnesses of passwords, at the same time as the habitual post-office box with messages will not fill to him of surveys.
