# Features available in a smart-meeting conference
During a conference in Smart meeting mode, users will be able to see and hear only the participants who are currently on the podium. The participants take the podium automatically according to the following rule: a participant who is speaking or sharing content (even without any voice activity) at the moment will be displayed in the layout instead of the participant who is now silent. The first user to be removed from the layout is the participant who has been silent longer than other presenters or started content sharing earlier (if the microphone was muted).
To learn more about the smart meeting mode, check the user guide to TrueConf for Windows.
You can “pin” any participant on the podium to make sure that this user is not removed from the layout even if he/she keeps silent. To do it, open the list of conference participants and select Pin on podium in the context menu.
