     <li>&xep0313; (MAM) is used for all history access, with each node being individually addressable for MAM queries. This simplifies implementation compared to MUC (which had a specialized and rather limited history retrieval mechanism).</li>
     <li>A client can achieve a 'quick resync' of a node by requesting just those changes it has not yet received, using standard MAM protocol. This solves the MUC issue of either receiving duplicate messages when rejoining a room or potentially missing messages.</li>
-    <li>Because MAM is used for history, only those nodes that have a 'current value' need to store any items in them &mdash; e.g., 'urn:xmpp:mix:nodes:presence' and 'urn:xmpp:mix:nodes:information' would store their current values (with older values being queryable through MAM), while 'urn:xmpp:mix:nodes:messages' would store no items.</li>

-        A user MAY subsequently modify subscription to nodes in a channel by sending a subscription modification request encoded as a &lt;update-subscription/&gt;  child element of &lt;iq/&gt; element.

Therefore it is will generally be necessary to include a nick when joining an channel.   If nick is missing on a channel where nick is mandatory, the join MUST be rejected.   Other error cases are dealt with below with the nick management commands.  Where a nick is specified, the join will only complete if the nick is accepted.   The nick used MUST be reported back in the join result.
