# Sharing and comments (/docs/sharing)



## A session link [#a-session-link]

Start a collaboration session on a dataset, then copy the link. A teammate who is signed in can join that session.

The host can set a participant to **Editor** or **Viewer**. You can save the session back to the source dataset, discard it, or leave it.

## Comments on a report [#comments-on-a-report]

On a report, the rail lists comments for that run. A comment can sit on a cell, a chart, or a section. You can reply, and you can mark a comment resolved.

Comments are stored with the report. Someone who can open the dataset in the organisation can read them.
