In my opinion, these 2 fields are vital, even for a
mail-orientated address book. Firstly, I like to keep
track of people's birth dates (ICQ automatically
notifies), to let them know I remembered, just for that
'personal touch'. A script/addition could later be
added to import/export vCal files for birthdates, for
interoperability with scheduling applications. Second,
knowing someones PGP fingerprint is just as important
as their email address. GnuPG does have a 'list keys'
feature, but I'd personally like to keep everything in
Thanks, and keep up the good work!
