Just be nice to each other. Don't use degrading, rude, nasty, vulgar, etc, language with others. This is a place to share and review code, not a place to pick fights and start flamewars. In other words, Treat others the way you would like to be treated. It's something we learned in Kindergarten, but it works for just about everything. Spam humor is accepted, and maaay be implemented as an Easter Egg.
