Hi,
I have a architectural question I wonder if someone can help with.
I want to create a basic address book for each members of my Drupal 6 site (every member would have his/her own book). In Drupal 5 there used to be a module called Addressbook but not in D6? I guess maybe it's pretty easy to do so with now Views and CCK? Can anyone tell me if that's the way to go or is there a D6 module which I've overlooked?

If I need to create one from scratch, could someone briefly describe to me what the architectural procedures would be?
