If I remember this right, there are several different actions that you can do during the day but they have to be supported by a majority. You propose an action:
Action Target [Your username] [PRO #] Names [CON #] Names
So if I wanted to spy you and you didn't want that, it would look something like this:
Spy flamebirde [Thalia] [PRO 1] Thalia [CON 1] flamebirde
This reads: Thalia wants to spy flamebirde. Supported by Thalia. Opposed by flamebirde. Something like that.
It's been a little while so that might be a bit off but I think that's what the format was. Does that make sense?
