In Channels with many members, everyone who has access can often modify Channel settings and shared Channel resources, for example:

Rename the Channel

Change the Channel description/topic

Add/remove Channel cards (bookmarks/notes/resources)

This creates governance issues for large Channels and makes it easy to accidentally break the Channel’s structure, remove key references, or cause confusion.

Requested capability:

Introduce Channel-level roles and permissions, similar to common team chat tools.

Minimum roles:

Channel Admin (full control)

Channel Moderator (limited management)

Channel Member (standard participation)

Optional: Read-only member (can view but cannot post or cannot edit Channel resources)

Suggested granular permissions (examples to implement):

Manage Channel settings

Rename Channel

Edit description/topic

Change privacy (if applicable)

Manage Channel membership

Add/remove members

Invite guests (where allowed)

Manage Channel cards/resources

Add cards

Edit cards (bookmarks/notes)

Remove cards

Message permissions

Post messages

Create posts/announcements

Pin/unpin items (if supported)

Default permission model:

By default, only Channel Admin/Moderator can edit Channel settings and cards.

Members can post messages but cannot change structural items.
