So I fixed a bug today on a feature I didn't know we had so I decided to let you all know about it in case you didn't as well.
On cube and apartment doors there is a 'buzz' verb. Used:
Or buzz 12
If the person who's cube it is isn't online, it will send them an e-mail letting them know someone wants to RP with them. Max 1 e-mail per hour so there won't be spam.
It also alerts anyone inside the room that the buzzer was pressed (similar to knocking).
