RE: Configuring MUC

This topic already discussed a while ago. You can find this through
mailing-list archive. For short, you should add attribute <roomlock/> in
your MUC configuration. This attribute is preventing users create a room.
You can also define users who can create rooms using attribute
<sadmin><user>...</user></sadmin>.

This is my MUC configuration:

	<service id="conference.my.portal.com">
          <load>
            <conference>../libs/mu-conference.dll</conference>
          </load>
          <conference xmlns="jabber:config:conference">
            <public/>
		<roomlock/>
            <vCard>
              <FN>Public Chatrooms</FN>
              <DESC>This service is for public chatrooms</DESC>
              <URL>http://my.portal.com/</URL>
            </vCard>
            <sadmin>
              <user>comm <at> my.portal.com</user>
            </sadmin>
            <history>500</history>
            <logdir>./logs/≤/logdir>
            <notice>
              <join>is here</join>
              <leave>has left</leave>
              <rename>is now known as</rename>
            </notice>
