Our documentation has a history of using a document's name as a way to link to it, such as "See [workers.md]() for details". This makes sense when you're traversing a directory of files, but less sense when the files are abstracted away - as they are on the documentation website. This PR changes the links to various documentation pages to something that fits better into the surrounding sentence, as you would when making any hyperlink on the web.

# Server Notices
|
|
|
|
'Server Notices' are a new feature introduced in Synapse 0.30. They provide a
|
|
channel whereby server administrators can send messages to users on the server.
|
|
|
|
They are used as part of communication of the server polices (see
|
|
[Consent Tracking](consent_tracking.md)), however the intention is that
|
|
they may also find a use for features such as "Message of the day".
|
|
|
|
This is a feature specific to Synapse, but it uses standard Matrix
|
|
communication mechanisms, so should work with any Matrix client.
|
|
|
|
## User experience
|
|
|
|
When the user is first sent a server notice, they will get an invitation to a
|
|
room (typically called 'Server Notices', though this is configurable in
|
|
`homeserver.yaml`). They will be **unable to reject** this invitation -
|
|
attempts to do so will receive an error.
|
|
|
|
Once they accept the invitation, they will see the notice message in the room
|
|
history; it will appear to have come from the 'server notices user' (see
|
|
below).
|
|
|
|
The user is prevented from sending any messages in this room by the power
|
|
levels.
|
|
|
|
Having joined the room, the user can leave the room if they want. Subsequent
|
|
server notices will then cause a new room to be created.
|
|
|
|
## Synapse configuration
|
|
|
|
Server notices come from a specific user id on the server. Server
|
|
administrators are free to choose the user id - something like `server` is
|
|
suggested, meaning the notices will come from
|
|
`@server:<your_server_name>`. Once the Server Notices user is configured, that
|
|
user id becomes a special, privileged user, so administrators should ensure
|
|
that **it is not already allocated**.
|
|
|
|
In order to support server notices, it is necessary to add some configuration
|
|
to the `homeserver.yaml` file. In particular, you should add a `server_notices`
|
|
section, which should look like this:
|
|
|
|
```yaml
|
|
server_notices:
|
|
system_mxid_localpart: server
|
|
system_mxid_display_name: "Server Notices"
|
|
system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"
|
|
room_name: "Server Notices"
|
|
```
|
|
|
|
The only compulsory setting is `system_mxid_localpart`, which defines the user
|
|
id of the Server Notices user, as above. `room_name` defines the name of the
|
|
room which will be created.
|
|
|
|
`system_mxid_display_name` and `system_mxid_avatar_url` can be used to set the
|
|
displayname and avatar of the Server Notices user.
|
|
|
|
## Sending notices
|
|
|
|
To send server notices to users you can use the
|
|
[admin_api](admin_api/server_notices.md).
