From the right pane of the chat room, I want to registration of the user

On the right side of the chat window of the chat room, list of users who are logged in will display, but there is a desire to add a contact from there.

Currently, I wonder Is there a way to achieve such as setting about this?

Openfire 3.9.0 Alpha

Spark 2.6.3 (Mac OSX 10.9)

Best regards
