MARC NOTHROP  A great way to deal with address details in raw formats (text files, etc.)

This was handy to have, when dealing with an email from a local group; I was able to select all addresses, and add them to a new Address Book group, in one move (although Panther Mail handles this, ie. select all addresses and click contextual menu, to add to AB.)

Naturally ContactCreator still works in other service-aware text fields, (e.g. Safari pages and form elements, TextEdit, iCal etc.)
