Treat all members and guests, without regard to their gender, race, creed, or political affiliation, with respect no matter what their knowledge and experience level happens to be.
Treat all Linux or FOSS questions as important to the individual who is asking. There may be a simple solution to you, so share it with those who are not as experienced.
Disagreements will eventually arise. Refrain from attacking or belittling those who disagree with you. Remember, Linux is about choice. YOUR WAY may be A WAY but perhaps not the ONLY WAY. Disagreement is no excuse for bad manners.
If you don’t know, ask for help. Don’t try and muddle through, reaching an end result that may or may not be correct. If asked for help gladly give it.
Take responsibility for your actions and statements. Refrain from those that will cause undue harm or embarrassment.
