Escape sequences that cause one effect on one device may do something entirely different on another. Do not use them unless you are sure they are standard. Avoid formatting problems. Adjusted right margins are hard to read without proportional fonts. Lots of vertical white space just takes up space.

Post new ideas. If you have something to say and no one else has said it, do so. But try not to repeat what has already been said, except in brief confirmation. Respond to the topic, not the person. Avoid ad hominem attacks and try to understand what the person is saying.
