The original proposed article carefully replaced turnchat with turnset and most of that has been un-done. The phrase "turnchat" should be rarely used as this will cause confusion in the case of an offline turnset or playsession.
As Ravensfire pointed out (both here and in the discussion thread) the term "play session" works better than both turnchat or turnset.
This looks like it might not pass as it is borderline right now. Either way, after the poll closes I will open a new discussion and propose a mock poll. Black Hole's concerns will not be addressed unless/until the discussion indicates wider support for his position.
Edit: to answer CT's question. The existing language can be abused by someone forcing public turnchats because that is the phrase used in the constitution. Reffering to an offline session as a turnchat is confusing at best.
