Evey other time I received swag, I had to confirm shipping information beforehand. Each time someone would send a helpful e-mail out, but I have yet to see one. In the contest post it said, "Winners will be notified via email within 10 days of the contest closing." I have checked a few times now and have not seen any messages from Stack Overflow employees, except for a handful of very suspicious messages in my spam folder saying things like We need your confirmation asap! I don't have a virtual machine handy at the moment and am hesitant to open any of them as there is no message preview. The senders are "Nancy" and "Lucy" with no other information.
Are those e-mails that might have come from Stack Exchange employees, or has the 6 to 8 weeks simply not past yet? (aka, are you guys just behind schedule sending them out?) I'm guessing terms like "winner" or "free" would be quick to be sorted into spam, so it is entirely possible they are the correct ones.
