Hey Bewildered,
Thanks for your advice. Re: minimum candidature, I've checked, and the min. registration period in my situation is 3 years, which is what I'm aiming for anyway.
As I'm presently located off campus, I no longer see my supervisor face-to-face. We communicate over email. So I wonder if the "net" amount of supervision will remain the same seeing how there are no office hours I can make use of. In fact me being off-campus is one of the reasons why I rather not pay full fees - I'm not there making use of any of the resources in person, so why should I!
