subject me not be all that clear but i hope this is!

Hey, i hope someone can help me with this.

is it possible to have different fields for different usergroups.

let me give you an example:

i have to groups of users,
1. teachers
2. students

from teachers i would like to know which classes they give and what they like about there course. this is in adittion to the normal user info.

from student i would like to know there background and what they whant to learn. this is also in adittion to the normal user info.

i hope this will give you a bit of an insite in what i would like to do.
i'm not intressted in ways to ad fields to the user accounts, just how to link this to the user groups.

thank,
Ben de Laat
