Starting to use the Fellowship Card
I recently became a fellow of the FSFE and so I received a nice letter containing the FSFE fellowship OpenPGP smartcard. After a quick visual examination I approved the card to be *damn cool*, even though the portrait format of the print of it still confuses me when I look at it. I especially like,…
