User stats are uploaded by Conference admins. When an admin uses EchoProducer on a Conference server for the first time the stats page will automatically add the new server to the database.
The Menu shows severs that have had activity within the last 12 hours.
Use the 'List All' option if you wish to see stats on all known Conference servers that are or have used EchoProducer.
