The latest version can be found here

Features:
GNOME interface
Uses the GNOME config file format (ooooohhhhhh)
Alphabetizes your entries
Ability to turn on/off certain confirmation options (awwwwwww ya)
Saves basic personal information (isn't that what you're using this for?)
Most importantly: If you're upgrading from the v.1.0 release, this WILL find your old databse and convert it.

Requirements:
GTK+ 1.2.0 or greater.
The basic GNOME libraries.  If you don' t install the pretty little pixmaps, those nice looking icons
at the top won't be there.

What's planned for the next release:
* Implement a fully featured search button, to search by any of the fields
* Support for multiple address books, along with merging of them
* Option to sort by last name, as well as first name
* Possibly the ability to edit/save/lookup databases on remote servers. Why? ummm, gives me a chance to practice TCP/IP programming, might be useful to some people.
