One word: Starts with D!

[ZetaAce]

That word is Discretion-

From dictionary.com (shout outs to the Great Keeby here )

dis·cre·tion (d-skrshn)
n.

• The quality of being discreet; circumspection.
• Ability or power to decide responsibly.

I'll use it in a sentence: Recently, there has been a lack of discretion on the GreekChat boards.

Sorors,

I'd just like to say thank-you for keeping it lovely on this board.

SZL,
