# Joining a Session

There are two ways to join a Session that somebody else has created. If someone chooses to include their Session in a public or Enterprise group list, you can go to the appropriate list in the ENGAGE app and join from there. For more information, see [Joining a listed Session](/engage/sessions/joining-a-session/joining-a-listed-session.md). If a Session isn't included in any list, then you can use the Session's unique ID to join. For more information, see [Joining with a Session ID](/engage/sessions/joining-a-session/joining-with-a-session-id.md).

{% hint style="info" %}
You can't join a Session that's full. For more information, see [Session capacity](/engage/sessions/creating-a-session/session-capacity.md).
{% endhint %}

When you join a Session that was created by somebody else, that person can control what permissions you have in their Session. If you are unable to use some features, such as to draw with the 3D pen or add IFX, then those permissions may be turned off for you.
