> Is there still a CmdrTaco user? http://news.ycombinator.com/user?id=CmdrTaco says no ..

The URL is case-sensitive, I guess the user registration is not:

http://news.ycombinator.com/user?id=cmdrtaco

That isn't the question... The question is, is there anyone squatting in the username cmdrtaco? I hope not, because that's just not cool.

There was someone squatting the username and they posted in the last Taco HN submission asking Malda to contact them via email (listed in their profile) to claim the account. He may not have seen that or just not mentioned in this write-up.
