If you are an owner or sub-owner of a house you can invite every single player to the house by first typing aleta sio, which brings up a window to manage guest list, and then typing asterisk symbol (*) in a new line.
You can also invite everyone, but some players (exclude just given players). To do so, type:
!(player name)
in any line above the line that has the asterisk mark placed. If you type the same in a line below the line with asterisk, it won't work.
