Did you srsly own auction.com??
A friend of mine owned a URL and was blown away when he was offered $5k for it... he laughed all the way to the bank.
windows.com
Ouch. Although with anti-squatting laws, he may have not been able to hold on to it anyway.
It's probably a blessing in disguise that I let the domain lapse. If I'd sold the domain for millions pre-bubble, I'd probably have blown the money on something stupid like Jazz season tickets. Then I'd have all sorts of regrets to post in this thread.
