Groups are to be understood as groups of audience members moving through your show. They have the following properties:

• Time - this is generally the time the group is scheduled to enter the show
• Colour - this sets the colour of displays and objects associated from the group
• Size - the number of audience members in the group; this can be set from the flow queue using the flow_enqueue command, or entered from a front-of-house remote station
• A chat log that moves with the group around remote stations - so show staff can see information on a group in their zone.
• A collection of tags that is derived from the chat log can be queried using the “contains” (^) operator in conditionals

Each time the first zone in the show flow advances (either with a single or universal advance), one of two things happens:

• If there are groups in the flow queue, a group is de-queued and added to the show flow
• If not, a group is derived from the group moving ahead of it using the parameters given when the flow was set up using flow_init
