I don't understand why I can't add users to my blog. I am registered as administrator, but I would really like to make it possible for some other people to make postings. I have tried to enter name, e-mail address and password of a new user, but when I press the button I just get a blank space, and the person is not added. Does anyone know why, and can anyone tell me how to add new users? I would appreciate this very much.
