Could you tell the difference between "sign up" and register? Some website use "sign up",Is that mean I should pay for the ID? Thanks for your reply!
Well, register mean 'Join Us' by filling up the long and hassle form, while Sign-up only need you to fill in your name and email address (Correct me if I'm wrong).
The terms 'Signup' is for online and 'Register' is for offline. Register could be use in online also. basically both are same.
