You can change settings for any one-to-one chat or group chat by clicking the gear icon next to the room name.
You can restrict access to a room to invited users only by choosing “Private (invite only)” in the room’s Security & Privacy settings. People who know the room link will not be able to access it unless they have been explicitly invited by email or ID.
If you add the room to a space, you can also choose “Space members” to allow access only to members of that space.
You can restrict access to a room to people with whom you shared the room link by choosing “Anyone who knows the room link” in the room settings. Choosing this option does not make the room public to the wider community.
To add your room to the server directory, select “Publish this room to the public in the example.com room directory?”. After you select this option, anyone searching for rooms on the server will be able to find it. However, they will only be able to join if you have not restricted access to invited users only.
If your room is listed in the directory, people will know that it exists, but they can join only if you allow access to anyone who knows the link.
Yes. If the room’s privacy and security settings set message-history visibility to “Members (full history)”, new members will be able to read messages sent before they were invited.
In end-to-end encrypted rooms, this feature is currently under development and will be available soon. When Ivan invites Katya to such an encrypted room, Katya sees a note on past-message pages indicating that Ivan shared them with her.
Because Katya was not in the room when previous messages were sent, Ivan provides her with the decryption keys for those messages. Most users will not need to think about this in normal situations and the messages can still be trusted, but from a security perspective it is important to be transparent about the origin of decryption keys and trust anchors. If Ivan acted maliciously and could find a malicious server administrator to cooperate with, they could manipulate those past messages together.
By contrast, if history visibility is set to “Members since invitation”, new members will not see messages sent before they were invited.
Note: changing room-history visibility does not affect messages that have already been sent. What matters is the setting that was active when a message was sent. For example, if history visibility was “Members since invitation” at the time a message was sent, that message will always be visible only to members who were invited or already members at that time. So if you switch from “Members since invitation” to “Members (full history)” on Tuesday at 10:00, future members will not be able to read messages sent before Tuesday at 10:00.
Note: in end-to-end encrypted rooms, history is available only if the new member is explicitly invited to the room. If the room allows users to join without an invitation and the new member joins that way, they will not be able to view the history.
No. Changing room access, such as who can join the room, does not automatically affect history visibility, such as who can see the history. For example, if visibility is set to “Members since invitation” and the room becomes accessible to everyone, a user still needs to join the room to see the history and will see only messages sent after they joined.
Also note that even if you later change history visibility to “Members (full history)”, that will not affect past messages. Those messages will still be visible only to the members who were invited or already members when the message was sent.
Making message history visible to everyone lets people see what has been discussed in a room before joining it. If you browse the room directory and see a room that might interest you, you can look inside and see what is being discussed without joining. This helps users evaluate a room before they join. It is useful for publicly available rooms that host public discussions, so users know what they are getting into before joining.
Note: for security reasons, this option is available only when the room is accessible to everyone and does not use end-to-end encryption.
By default, a room has an unattractive identifier that is barely readable by humans. Assigning a room address gives the room a simple identifier, making it easier to share a link. Addresses are tied to the server where you are registered, for example matrix.ucmeet.org if your ID is @username:matrix.ucmeet.org. A room can have several addresses on the same home server and addresses on different home servers. It is just a convenient entry point, but it is required if you want to make the room available in ways other than inviting users.
In Favorites, you can pin and organize important rooms so they appear at the top of your room list in UCMeet.
The Low priority section lets you organize your room list by moving rooms you consider less important to the bottom of the list.
The History section lists all rooms you have left and lets you view the history of your time there. You will not see new activity in those rooms, only what happened before you left.
In Roles & Permissions in the room settings, you can set the privilege levels required to perform different actions in the room, such as sending messages, banning or removing members, editing messages, updating room settings, inviting new members, and more.
