According to the pgp help for the preference item, which is called
"Always encrypt to default key":

"When this check box is selected, all the e-mail messages or file
attachments you encrypt with a recipient’s public key are also encrypted
to you using your default public key. It is useful to leave this setting
turned on so that you have the option of decrypting the contents of any
e-mail or files you have previously encrypted."

I've encrypted the above with Adam Back's key (I don't have your's)
below, so supposedly he will be able to decrypt it and if I check my
copy of this message I should also. I'll let you know below.
