What exactly does your bingo startup do again? ;)<p>I finally broke down recently and made a compendium of all my username/passwords combinations in an encrypted file. It was eye opening when I finally saw how many passwords I actually use and (mostly) remember. The repetition frequency was higher than I would like, but I'm careful to never use the same password for a site account and the associated email address(es). Unfortunately, I can't say the same for my relatives and friends...
