Bwahahaha....
I don't know if I've ever told you this, but when I went to sign up, I was planning on using your exact screenname. After several denied attempts at signing up using different variations incorporating #3, I decided to come up with another screen name. Right at that moment, fox was replaying a President Bush speech and I swore I heard him say "We must remain viligant", which inspired me come up with viligantcitizen.
Now I've never claimed to be a genius, but I've always considered myself to be good at spelling, and the thought of looking it up in the dictionary never crossed my mind, until three weeks later when a poster brought up the typo.
After dictionary.com confirmed my error, and a short period of "How could I be so stupid?" contemplation, I decided to leave the error be as a reminder to myself to always verify and proofread.
