Users with no profile access but change email

[NetRover]

I have a Free usergroup and a paid subscription group.

I want the free group to have either a limited profile or no profile access. I know with no profile access they can't change their email. I thought one way would be having the edit email/password link in one of the main control panel options.

Someone may have alternative advice if I explain my reasons and what I need to achieve somehow:-

My profiles can be quite detailed and personal so I don't want free members to be able to enter all the details. I have my free members so they can't view or edit profiles because of these reasons.

It would be nice if Free members had limited profiles and could still view profiles but only for the Free members. Paid members to have the full profile and view all member profiles.

The template option sounds good but how would I find out more about doing it from a newbie perspective.
