496. Briefly: New email -- adding to PGP/GPG key and changing email account order in Thunderbird

I've created a new email address to move my email correspondence away from google as much as practically possible.

gpg
I've already got a gpg key pair, but I'd like to add the new email address to it.

First find out what you key id is, then add another user id:

 gpg --list-secret-keys

/home/me/.gnupg/secring.gpg

Simple, yet more complicated that it needs to be: http://sidvind.com/wiki/Thunderbird/Change_account_order

Go to Edit, Preferences, Advanced, General, Config Editor.

Search for mail.accountmanager.accounts, and edit the order of the accounts.

Note that the default account (mail.accountmanager.defaultaccount) will always show up first, regardless of the order you set. Restart thunderbird and the changes should take effect.
