On the topic of the room setup, I like the idea of the 3-person group/rooms. It'll allow for some interesting character-building time and, depending on who gets grouped together, it would be hilarious to see how these characters handle the living situation. 

About discord, I'm not opposed to it. I am quite active on Discord myself. Equally so, it's been so long since I've been in a roleplay with so much OOC chatter. It's quite nostalgic. Nevertheless, I'm indifferent.
