 * <p>Joins the workgroup queue to wait to be routed to an agent. After joining

 * the user can leave the queue: <ul>
 * <p/>
 * <li>The user is routed to an agent, which triggers a GroupChat invitation.
 * <li>The user asks to leave the queue by calling the {@link #departQueue} method.
 * <li>A server error occurs, or an administrator explicitly removes the user
 * from the queue.
 * </ul>

 * A user cannot request to join the queue again if already in the queue. Therefore,
 * this method will throw an IllegalStateException if the user is already in the queue.<p>
 * <p/>
 * Some servers may be configured to require certain meta-data in order to
 * join the queue.<p>
 * <p/>
 * The server tracks the conversations that a user has with agents over time. By
 * default, that tracking is done using the user's JID. However, this is not always
 * possible. For example, when the user is logged in anonymously using a web client.
 * In that case the user ID might be a randomly generated value put into a persistent
 * cookie or a username obtained via the session. When specified, that userID will
 * be used instead of the user's JID to track conversations. The server will ignore a
 * manually specified userID if the user's connection to the server is not anonymous.
 *
 * @param metadata metadata to create a dataform from.
 * @param userID   String that represents the ID of the user when using anonymous sessions
 *                 or <tt>null</tt> if a userID should not be used.
 * @throws XMPPException if an error occured joining the queue. An error may indicate
 *                       that a connection failure occured or that the server explicitly rejected the
 *                       request to join the queue.
