A message without an instance specified will default to the instance
“personal”.
+You can send zephyrs to individuals (as opposed to classes) with:
+
+ :zwrite USERNAME
+
+### Aside: zephyr triplets
+
+All messages are actually sent to a "zephyr triplet" -- a class, instance, and recipient. Subscriptions are also made to zephyr triplets. The recipient can be either "*" -- to indicate a broadcast message -- or a specific individual.
+
+When sending, the default class is "message", instance is "personal", and recipient is "*". `zwrite` supports sending to arbitrary triples with `:zwrite -c CLASS -i INSTANCE USERNAME` -- the two examples above use the defaults for the parts that aren't specified.
+
+For subscriptions, the class must be specified. You can specify all instances on a class with "\*", or specify just one instance. You can only sub to recipient "\*" or your own personals (indicated by "%me%").)
+
+### Common classes
+
Some common classes include:
<strong>help</strong>:
phrases and words being thrown around. Some of these include:
<strong>i,i foo</strong>:
-> picked up from CMU zephyrland and means "I have no point here, I
-> just like saying:". Sometimes people simply use quotes: `"foo"`.
+> USENET saying picked up from CMU zephyrland that expands to "I have no point here, I
+> just like saying:". Sometimes people use
+> [scare quotes](https://en.wikipedia.org/wiki/Scare_quotes) (e.g. `"foo"`)
+> for similar purposes.
<strong>mix</strong>:
> If somebody accidentally sends a Zephyr to the wrong class or
> You may see an instance change from `-i foo` to `-i foo.d`. This
> indicates a deviation or tangent from the the original topic.
-<strong>starking</strong>:
-> Answering a question or replying to a topic to a topic several hours
+<strong>.q</strong>:
+> Simiarly, `.q` at the end of an instance name indicates a quote.
+
+<strong>to Stark</strong>:
+> To answer a question or replying to a topic to a topic several hours
> (or days, occasionally) later. The term originates from Greg Stark,
> who would often reply to zephyrs hours or occasionally days later
> without seeing if anyone had answered yet, or worse, if the instance
> had moved on to an entirely different topic.
<strong>ttants</strong>:
-> Literally, "Things That Are Not The Same".
+> Literally, "Things That Are Not The Same".
<strong>prnf</strong>:
-> Literally, "Pseudo-Random Neuron Firings".
+> Literally, "Pseudo-Random Neuron Firing".
+
+<strong>eiz</strong> or <strong>eip</strong> or <strong>else</strong>:
+> Instances used to comment on discussions on other classes in Zephyr without
+> linking to the original source for reasons of privacy or discretion. "eiz"
+> means "Elsewhere in Zephyr", "eip" means "Elsewhere in Personals".
+
+<strong>eim</strong>:
+> "Elsewhere in Meatspace"; instance used to comment on events not on Zephyr.
-There are many other acronyms that are used; if you don't know what it
-means, try using the `whats foo` command at an Athena terminal. If you
-don't have the command, run `add sipb` first.
