This one for the code monkeys (Hi Thotter)
If it doesn't exist, I want to suggest a %room.guestlist% variable that returns a string containing every guest member's name. This will be useful for making if checks in playerhouse scripts that you want to be restrict to guest members. Returns an empty string if not a crash proof room.
While you're at it how about a %room.house% that returns 1 if it is a crash-proof room and 0 if not (useful for insanity checks) and %room.owner% that returns the name of the owner (also returns an empty string if not crash proof room.)
If these already exist, please let me know
