I didn’t know I had one, but then he ordered some Mac stuff from a Yahoo store and accidentally entered my .Mac email address instead of his very similar one. Since the shipping and billing addresses were in Boca Raton, Florida, and I’m in California, this looked an awful lot like identity theft, which makes for a lovely way to spend a Friday evening. After calling all of my credit-card vendors to check for suspicious charges, changing several passwords, and other financial fire-drilling, I thought to look up the phone numbers from the invoice with anywho. Sure enough, there’s a Jay Greely in Boca Raton, and he lives at that address.
Update: Just talked to Jay’s wife, and it turns out that they bought their first Mac yesterday, and he apparently misremembered their shiny new .Mac email address.
