Went by the local thrift store on my way home today, and while I was there, I saw a computer. Just had to mess with it a bit.
Well, there were TurboTax records on there from the past 4 years or so, not to mention all of the personal info. in My Documents, too. There was a resumé, some other types of tax records, addresses, etc. I know there had to be social security numbers on there - more than likely in the TurboTax records. I let one of the staff there know, and they said that none of them knew anything about computers, and please do what I could. I told them they should pull it off of the shelf, but I did delete files at least, and emptied the recycle bin.
Not sure what else I could've done, but it was better than it was.
