What I want is to use the custom user field option to create a new field (Home Address) where members of our partly private forum can fill in their contact information for other private members. Part of the forum is public, with partly public members. So two questions arise; - is it possible to have certain custom user fields only available for certain user groups? - is it possible to hide certain custom user fields for anyone not part of a certain user group? I can imagine this needs to be done with an addon....but I was wondering it it'd be possible / hard to do at all?
