Your Studio is your own private room in Sessionwire. Open it from the Studio icon in the left sidebar. Its address never changes, unless you change your Display Name, so people can always find you there.
When you're on your own, the bar at the bottom of your Studio shows:
Once someone joins, the bar changes. As the Host you'll see:
Guests see the same bar without Host Ctrl and Waiting Room, and with Leave instead of End.
To hide the labels under the buttons, turn on Hide Button Text in Session Settings.
To change someone's role, open Studio Chat, click ... next to their name, and choose Make Audience, Make Moderator or Kick.
Click End to end the Session for everyone. A Guest who clicks Leave only leaves themselves.
On the free trial you can host for 40 minutes in any 24-hour period. On Basic and Studio, a Studio closes after 24 hours, long after most Sessions are over. To carry on, invite your Guests again.
Before anyone joins, click Theme and pick a background colour for your Studio.
