Please read the Presenter basics to understand what it is.

Note that the columns in the Presenter window are actually anonymous players but by default they're set to Role 5.

A great first step to raising your game beyond the basic Presenter setup is to have a single device in the room that receives emails or phone calls. This creates a good mix of you managing a room discussion and interrupting the discussion with an urgent message or action.
To do this, assign positions to the columns and to the device and ensure that the content you publish goes to those specified positions. This will mean phone calls, for example, only go to the device and not to the columns.
