Hi,I came across this website http://forums.xisto.com/no_longer_exists/ which offers an innovative login system.In the traditional login system, a user is asked to enter a username and password besides many other personal information.In this website, to register the site creates an ID file that the user can download to the local hard drive. After registration, to login to the website, the user has to simply upload the registered ID file (browser and select ID file from local hard drive) and click on the Login Button.The user is then taken to the website which seems to be a search engine and submission service.All entries made in this site are then tagged on the basis of this ID file.Guru
