DOC RENAUD  The kind of thing you didn't realize you need it, until you got it.

Brilliant !

DESIGN-Q  Does not work with my system:

PowerBook G4 1.25GHz OS X.4.8

Address Book v4.0

I have another Address Book plug-in installed:

Age v1.0.1 [http://www.macupdate.com/info.php/id/18274]

Have not try with only this plug-in installed. Does not work when both are installed - decided to remove this one and keep the existing.

APPLEDOGX  Great! Even seems to use the right date for Chinese horoscope animals. Many programs seem to get the animal wrong before Chinese new year. I have had to use other programs to get much of what this gives. It would be great if you could display the information without having to click the mouse, right in the address book, though.

CHARNECA  Work fine in my Mac OS 10.3.9 :)

DAMACGUY  Simple and straight forward. Love it!

Only giving a 4 for features. it'd be great if the info could be displayed without involving a mouse click, but this is the next best thing.

Thanks!
