Last week my Yahoo account got hacked. Somehow, everyone in my Yahoo contacts list received spam sent from my account. After getting a call from Mom, I checked the account, and found the offending e-mail in my Draft folder.
So I immediately changed my password, and began doing that for all of my accounts. Granted it used to be just a single uncapitalized word, but it is still disturbing to have it happen.
So now I'm in that limbo of no remembering which accounts I have changed the password for. I log on somewhere, or try to, and find out if its the old weak, or new strong password.
