Before I unsubscribe this thread, I just wanted to give a few tips to other migraters about my experience. I really miss categories and contact portraits. It is extremely useful to be able to group people in more than one way. e.g. it someone is in your family and on your soccer team, they would be in both categories. TBird does not have categories. You can simulate a single category by making address books that map to a category. So I have made an address book named after my soccer team, another named for the waiting list of people who want to join, and others. Then I copied from the imported address book into the appropriate "category" book, and then deleted the original contact card. Unfortunately, there isn't a "move" feature in the address book.
Second, the portrait helps me know what someone looks like before I meet them. Back to my soccer team. I recruited completely unknown people to the team, and was able to recognize them at the field using the portrait images that they had sent to me. Right now I do not have a work-around for this missing feature. Though if I can use HTML in the contact info, I may be able to put a img tag in there that links to their image file.
