| /datum/say_channel | Say channel datums govern the dissemination of messages to registered listen input module datums. In its simplest form, this
involves a say message datum being passed from an output module to a channel, and the channel then performing shared input
formatting before passing the say message to registered listen modules. Say channels also determine whether a message should
be affected by output and input modifiers, and whether the sender should display a speech bubble and play a speech sound. |

| /datum/say_channel/global_channel | Global say channel datums act as optional parters to delimited say channels, with the delimited channel passing all messages
sent over it, irrespective of subchannel or range, to the global channel. In turn, any message sent to the global channel will
be sent to all listeners on the delimited channel, irrespective of subchannel or range. |
|---|
| /datum/say_channel/delimited | Delimited say channel datums, by some criteria, restrict the number of listeners that a say message is passed to. This typically
manifests as only sending messages to listeners within a range of the speaker, or only sending messages to listeners registered
to a specific subchannel. A global say channel datum may be associated with a delimited channel, which will receive all messages
sent over the delimited channel and in turn may send messages to all listeners. See /datum/say_channel/global_channel. |

| /datum/say_channel/delimited/local | Local say channels are a form of delimited channel that restrict the number of listeners that a say message is passed to on the
basis of range. How this range is calculated may be altered by overriding GetAtomListeners(). |
|---|
| /datum/say_channel/delimited/bundled | Bundled say channels are a form of delimited channel that restrict the number of listeners that a say message is passed to on
the basis of which subchannel a listener is registered to. Unlike say channel IDs, subchannel IDs may be defined arbitrarily at
runtime; subchannel IDs are commonly BYOND atom references to some shared datum among listeners. |
