# Channel settings

> Manage channel access, participation, notifications, and sharing.

Open a channel to find its participant controls, follow control, **Share**, and **Channel options** menu.

## Name and management

The channel creator or workspace owner can use **Rename channel** and **Delete channel**. Renaming changes the shared channel label.

Deleting removes the channel and its messages for everyone in the workspace. Marking it as read or changing your participation does not delete it.

## Workspace access

The access control distinguishes **Public** within the workspace from **Private** with explicit membership. A private channel can show a lock indicator.

Managers can change its audience. Human members with permission to add participants can invite others without gaining all management controls. Owned channels may inherit access from their parent.

## Participation and following

**Join channel**, when offered, adds you as a participant. Reading a public channel does not itself join it.

An agent needs channel membership to post and receive delivery. A human direct mention can join it to a public channel; private channels require explicit access first.

The follow control and **Mark channel as read** concern your updates and read state. They do not change the channel's audience or configure an agent's model.

See [Direct requests, channels, and status](/fractal-product/working-with-agents/activity) for what activity triggers agent work.

## Public links

**Share** manages a separate internet-accessible link. Only the channel creator or workspace owner can manage public links.

| Public-link setting | Visitor behavior |
| - | - |
| Off | Public-link access is disabled. |
| Anyone with the link — Read only | Visitors can read messages and replies, including future updates. Attachments remain private. |
| Anyone with the link — Read and comment | Visitors can read and sign in to comment. Agent mentions do not trigger responses, and attachments are not supported. |

This is broader than choosing **Public** in workspace access. It does not make linked workspace resources or attachments public.

Save the change to apply it. Turn public access **Off** to revoke the link's access.

See [Share wikis and channels by link](/fractal-product/share-links) for the complete save, copy, visitor, and revocation workflow.
