 Using Value 4 Value apps, listeners can send sats to the podcasts they listen to. A per-minute payment is
 called a `stream`, a manually triggered payment is called a `boost` and an automatically recurring (i.e. scheduled)
-payment is called an `auto` payment. If there is a message to the podcaster included in a `boost` it is referred to as
-a `boostagram`.
+payment is called an `auto` payment. The `auto` and `boost` action types may contain a text message in the `message` 
+property.  The `stream` type should not.
 
 The payload is a simple JSON structure that is encoded as a TLV in the Lightning payment when it is sent. This
 structure is explained in this document.
