1.             How a "good Dom" interacts with other Dominants.....

Like a person.  :)))  Getting past what seems to be an almost inherent need among "dominants" to 'one-up'.  Acknowledging someone's' self-declared dominance only when it has been demonstrated.  Not poaching; that involves not interfering with the mental, emotional or physical aspects of a submissives space that another dominant may be attempting to touch, without a clear understanding of who is where or what.  Not judging; that means not kink -bashing or voicing *my* opinion about what they do or don't do or how they do it, unless I believe harm (mental, emotional or physical) is occurring.  Being a sounding board and being willing to share ideas, techniques and resources.

2.             How a "good Dom" interacts with submissives who do not belong to Him.....

She <chuckle>  treats them like a person, with their own rights, desires and opinions, as they are and have those things. <smile>  She may show her dominance in ways that are part of her personal makeup, but should not seek to use a submissive to 'demonstrate' dominance. 

3.             How a "good Dom" introduces a "newbie" to the lifestyle:

                              PUBLIC LIFESTYLE practices...

                              PRIVATE LIFESTYLE practices.....

Like a person who wants and/or needs to be educated.  Beyond that nutshell, I am going to bail on this one, as my response would take an entire thread.  <chuckle>

<---- has rather lengthy and umm...personal opinions on the newbie thing :)))

4. How a "good Dom" conducts Himself at D/s social functions (non-play as well as play parties)......

 Like a person.  :)))  Demonstrating courtesy and respect to those who merit it, be they dominant or submissive.  Willing and looking to meet and interact with people... not labels.   Asking a person where they fall in the grand scheme of things instead of assuming. Recognizing that everyone who is doing this is an adult, choosing to do it, but at the same time, acknowledging that not everyone is at the same experience or intensity 'level' as everyone else, and *respecting* that instead of perceiving it as some sort of challenge to ones "dominance" or lifestyle.

5. (Open to any and all suggestions on points I've left out).......

How to not assume gender based roles. How to acknowledge that the vaunted "community" includes many whose kink or style doesn't fit neat, pre-determined roles and/or labels.  The perceived role or duty of a dominant in regards to what is often assumed to be automatically due a self-labeled submissive... i.e., "protection", (ye olde white knight thing), and how that differs from what is "due" to someone who labels themselves differently .  And oh yeah... how to deal with switches.  <chuckle>

I respect the idea, as long as this "code" doesn't become... judgmental.  That's going to be a fine line to walk. Good luck. <smile>
