When involved in a conversation or more importantly a fight, if one member of the event is away from the keyboard then that rp must halt or find a way to work around that person. They dont disappear or take blows automatically. For example if I am in a fight with Victor and he decides to take off for the day then our fight is on hold (So i could post one last attempt attack which i then wait for him to return and respond to)
In conversations this rule can be worked around. For example if the conversation is in between myself Victor and Anzidon and I decide to take a break, Anzidon can say something along the lines of "Now ignoring Asuma Anzidon asks Victor....".
This rule will not be heavily enforced as far as conversation goes, its merely proper behavior, but in combat situations this is perhaps one of the most important rules
