<div class="wiki-content maincontent"><p>ActiveBlaze supports group membership using a GroupChannel - which can be created from a GroupChannelFactory.<br clear="none">
You have to explicitly say which group you want to join/leave - and you can join multiple groups.<br clear="none">
Each GroupChannel has both a globally unique id and a name.</p>
