I can house limited people due to 5 people living in my house already. Sleeping arrangements are either going to be comfortably on the basement floor (my little brother's room, Crow in Dr.X's video) if he approves or on the floor of the living area downstairs / two couches.
I don't personally mind people staying up late prior to an event, but if I have roomates that want to sleep and/or have work in the morning, they take precedent. I don't forsee anyone complaining as that's never happened before when we've housed earlier, but just as a warning I might have to tell you to shush and turn off the setups til the morning.
It's my home, so you're responsible for what you do in it. You break it, you buy it. I have a small dachshund named Lucca, so if you are allergic to dogs I can't do anything about it.
Everyone who stays the night is required to have debates with Dr. X about the aspects of Brawl that are better than Melee.
Priority is only to people who are coming from out of town. If you're lucky and there is time we'll cook breakfast and maybe grill hamburgers. If I ask you if you like spicy things say no or I'll start opening some bottles of hot sauce.
Dr. X will be coming to me with people that need housing and I'll approve them if we have space. I don't really have a problem with anyone in the smash community despite how fun it is to mess with them so no one would be denied housing because I tease them on the internet. :B
Except for the people that steal and break stuff. Those people can't stay. >:|
Edit:
Dr. X made a video about suicides because otherwise it would have been a video of him on the receiving end of combos.
