Matrix Rooms Settings

How can I change the settings for a specific chat or room?

You can change the settings for any one-to-one chat or group room by clicking on the cog icon next to the room name.

Can I restrict the access of a room to a given set of people?

You can restrict the access of a room to people who have been nominately invited by selecting the “only people who have been invited” option in the room settings. People knowing the link of the room won’t be able to access it if an invite hasn’t been explicitly sent to their email or id.

Can I limit the access of a room to people knowing its existence?

You can restrict the access of a room to people with whom you shared a link to the room by selecting the “anyone who knows the room link” option in the room settings. Selecting this option will not make the room publicly visible to the rest of the community.

Can I make a room publicly discoverable?

You can get your room listed into your server’s directory by checking the “list this room in the (your server name's) directory”. By checking this box anyone making a search on the server will be able to see it. However, they will be able to join only if you haven’t restricted the access to it to people being invited.</your>

Will anyone be able to join my room if I list it in the directory?

If your room is listed in the directory, people will know it exists but they will only be able to join it if you allowed the access to it to anyone knowing the link.

If I make the room accessible to anyone, will new joiners be able to read the history?

It depends on how you configured the history visibility for the room. By default every member of the room can read its history. But you can decide that new joiners will only see the history they are part of, I.E. Members will only be able to see the history of the room since they were invited (or joined, both options are available) . ‍ However it is important to note that these settings are not retroactive and only apply from the time they are selected: if you have a discussion with the history being visible to every member since the start, then change it to discuss an important matter so that people only see the history from the time they joined, new members will have access to all the history before you changed the option.

Why would I want to make the history visible to anyone?

Making the history visible to anyone means that people can see what is being said in a room before joining it. So typically, if you are browsing the room directory and see a room which might be interesting, you will have the opportunity to “peek” into it, having a view of what has been said without joining it. This gives users the opportunity to gauge a room before joining. It is a useful option for rooms publicly listed and hosting public discussions, or for people you share your room link with, so that they have an idea of what they’re going into before joining.

What is a room address?

By default the room has an ugly identifier which is barely human readable. Setting an address for a room allows you to give it a simple reference making it easier to share a link to it. The addresses are linked to the server you are registered (e.G. Matrix.Org if your id is @username:matrix.Org). A room can have different addresses on the same homeserver and addresses on different homeservers. They are just a user friendly entry point, but are required the moment you want to make the room accessible in other ways than by inviting users.

What is a favourite room?

The favourite section allows you to pin and order important rooms which will be displayed at the top of your riot room list.

What is a low priority room?

The low priority section allows you to declutter your room list by moving rooms you consider less important to the bottom.

What is the “historical” section?

The “historical” section lists all the rooms you’ve left and allows you to access the history you have there. You won’t see the new activity in these rooms, only what happened before you left.

As a room admin, can I decide what members can do?

In the roles and permissions section of the room’s settings you’ll be able to configure the privilege level are required to perform various actions in the room, e.G. Send a message, ban / kick members, redact messages, update the room’s settings, invite new members, etc..
