I use BBDB (Big Brother Database) with Gnus. This creepy-sounding package stores information about contacts. For example, I'll store their mail aliases; IRC handles; software they maintain (especially within GNU); organizations they're a part of; desired gender pronouns; country/state; and other non-sensitive data.

Importantly, though, I want to respect the privacy of individuals, so I added a `.gpg` suffix to my bbdb file so that Emacs encrypts it (using my Nitrokey).
