Jyothivas is right. I only want to add one more comment about the mail. You can switch off emails by setting the configuration properties "sendEmailAtRegister" and "sendEmailWithVerficationCode" to 0.
The configuration properties can either be editted in the Openmeetings interface at: Administration -> Configuration or directly in the database in table "configuration". And they are also set during the installation process (in case you decide to go through the installation process once more). -- You received this message because you are subscribed to the Google Groups "OpenMeetings User" group.
