A noder is
stealth mode is one who has his Chatterbox turned off and always clicks
Don't display in "New Writeups" when making a new node. He also sometimes tries to
masquerade as other noders and quickly turns off his
monitor when other people come into his room so that no one can see that he's noding.
Some might say he's antisocial or paranoid, but no - that's stealth.
