15## Why?
16
17Honestly I don't know why you'd use this function. I just made it as a joke to link to it from [@stevekrouse.dm](https://www.val.town/v/stevekrouse.dm). I guess you could also use it a joke to send data you want to call attention to the fact that you very much don't care about it, ie I **really** don't care about the price of bitcoin:

11## Protocol
12
13Expose a `dm` function on your namespace that that accepts messages and some authentication data (described below). The easiest way to accomplish this is to fork this val.
14
15What you choose to do with direct messages is totally up to you. At the moment, I email myself your message and save it to a private array val. You could forward it along to yourself some other way, batch up messages to get a daily summary email if you're Mr. Popular, or send them to [/dev/null](https://www.val.town/v/stevekrouse.devNull) if you're Mr. Antisocial.
17## Authentication
18
19This protocol uses [my Val Town public key auth scheme](https://blog.val.town/public-key-auth-val-town-users-can-be-your-users), so you'll need to follow the first two steps of that blog post – (1) generate a keypair and (2) publish your public key – to authenticate to this function.

21## Usage
22
23You can call this function via the [@stevekrouse.runValAPIAuth](/v/stevekrouse.runValAPIAuth) helper:

25```js

25### 4. Fork this val & run it
26
27Save your own private version of a `telegram` function to your account by forking this val: https://www.val.town/v/pomdtr.telegram
28
29### 5. Send a test message!
