There are times when we need a registered member on our website that allows one to access a page that is only displayed if the user is logged into our website. Are normally we use the registration form to register a new user into our website. With the rapid development of the internet of course one sometimes forgets the user and password that was created on a website because of too many usernames that should be remembered. We can create an alternative to our diwebsite member registration using facebook connect. so users no longer need to remember lots of usernames and passwords simply by facebook account.
how to make it. thanks: D
