I agree with [@Aristo], as much as I like to create a chat, it would be kind of redundant seeing as we can freely talk here. I'd like to reserve a chat if we needed to discuss things real time, or to create collabs. Maybe when such things come. 

and [@Erode] I count inactivity to be a whole week, same with rounds. That won't mean there will be times when players are allowed post multiple times during an event. This is when there is no direct urgency, where posting structure and action order isn't really that important to the narrative. For example, during downtime, your characters may be able to talk amongst themselves freely. Sort of like now. 

Keeping courtesy to others in mind, of course.
