Confusing Registering Screens

Registering for the first time is really confusing. Currently, a user can register in several ways:
(a) Through selecting Register
(b) Through the Login or Sign Up Screen then selecting Register
(c) The template where they can chose As a Employer or Job Seeker

If they register through the template, they can choose whether to select whether they are the Employer or Job Seeker – HOWEVER, if they chose (a) or (b), it takes them to what appears to be a generic login screen. However, when a user registers using this, they register as an Employer.

For a first time user, this can be really confusing.

(a) Can you please make it so that whatever way they chose to register, it gives them only two options – Employer or Job Seeker.
(b) As a side issue – when a user is logged in and they click on “Login in” or “Sign Up” or “Register” there is no message to say that they are already logged, or are already registered, and it allows them to login and register again
(c) A potential security issue is that a new user can register their details from another users account without the user having to log out.

If I have got this wrong, or not using the software correctly, please let me know

Kind Regards
