@Migukin it's not a dumb question. :) It wouldn't be centralized. It would be done on each instance by the admin.
@frankiesaxx so you just wouldn't have that functionality in some places and it would have be backwards compatible. I only ask this should someone decide to upgrade this concept to IRC / Slack like live chat, with rooms and stuff.
