I have no experience with older versions, but I would think that they are somewhat similar, at least with administration.

I tried to login as administrator but it won't let me create a user/password. I have tried all possible combinations. I have a username and password, but it is not for the administrator. I have no clue how to make/get an admin account, or retrieve one that I might have unnoticeably made. Is there an email password for Administrator account?
