3. Using your own special pre-installed user registration system through embedding your own classes in Glassroom system.

 If you need special features in your registration system like password encryption, login time scheduling, etc. and you need to have a more complex interface between your existing registration system and your chat server, you can write your own interface and embed it in Glassroom server. The interface is a Java class file containing some methods (functions) for authentication, profile manipulation, etc. Glassroom uses two internal interfaces by default : InternalAuthenticator and InternalDBInterface. You can derive your classes from them, and make your own changes in them.

If you plan to use this feature and need more help please visit the forum
