title: XMPP Reserve nickname in MUC service
body: <p>I am currently implementing an MUC(Members only) application for the mobile platform. I am able to get the MUC working and the mobile clients are able to communicate with one another.</p>
  
  <p>The problem i am trying to solve is that i would like an user to reserve a nickname in the MUC service which is valid across all rooms, so that nobody can disguise him in the chat. I have done a lot of reading but haven't found any appropriate example on an user can reserve a nickname across all rooms.</p>
  
  <p>Any help in pointing me to the right documentation would be appreciated.</p>
  
  <p>Thanks,
  Mithun</p>
