I'm using:
Joomla 1.5.12
CB 1.2.1
CBSubs 1.0.1
Rating Field 1.0 RC

There are 3 CBSubs groups (bronze, silver, and gold) that belong to the Registered Group.
There is 1 CBSubs group (professionals) that belongs to the Admin Group.

There are 2 rating fields.
One (Public Rating) appears on the bronze, silver, and gold member profiles and can be rated by any registered user.

The other rating field (Professional Rating) also appears on the bronze, silver, and gold member profiles and is viewable by all but we would like it to be only available for rating by members of the Professionals group. Is it possible to setup this special Professionals only rating field with the above configuration? If not, any ideas on modifying the code?

I was thinking of adding a third type to the rating field call "Stars - Professional Rating" but before I start messing with the code I thought I'd check the forum first.

I have tried the tabsfields protect plugin. I'm using it with some other fields (great feature). My problem is that I can control when the rating field is displayed but not who can click it. Currently, if it is displayed then anyone who is registered can click it and have their rating recorded.

What I want is for anyone who is registered to be able to see it but only members of the Professional CBSubs group to be able to click it and have their rating recorded.
