From each user <math>i</math>. The joiner makes a session for each <math>sid</math> which contains them as a participant, the user initiates a session and gathers shares. '''When a session receives all shares, it computes the session key and becomes the current session.''' All other sessions can remain in limbo or get discarded based on the memory capacity of the implementation and security requirement.

'''If <math>U_l</math> , currently in room the session, signals to leave the room , a new session <math>S_l</math> is created. Each Furthermore, each session <math>S_j</math> in-limbo which has <math>U_l</math> as participants, results in the creation of new session <math>S_{j'}</math> with user <math>U_l</math> omitted. and <math>S_j</math> is marked as dead.'''

The user <math>U_i</math> sends the shares and authentication token necessary for each session. The first session which receives all confirmations will become the main session, and the joiner user of that session becomes the current session. '''All other <math>S_j</math> results result in new session sessions <math>S_{j''}</math> to which <math>U_{joiner}</math> is added. previous "Previous active (current" ) session of the room becomes in-limbo.'''
