(Profile Field Category) Explanation text
 

On the privacy settings its important to users what the category actually contains. If I have a

• profile field category A which includes the profile fields a,b,c,d,e and
• profile field category B which includes the profile fields f,g,h,

it is important that the user knows when changing privacy values for the category A, he sets the privacy settings for a,b,c,d,e. And not for f,g,h.

Therefore either a free text, of a list of the containing profile fields within each category should be shown on the privacy page. I'd far prefer an automatic solution here.
