The Privacy dialog allows you to control some of the information which other citizens of Active Worlds can learn about you. It also lets you control whether or not people you have not specified individual settings for in your contact list can send you files or join requests. To adjust your privacy settings, go to the Options menu and select Settings..., then click on the Privacy tab:

Defaults

Hide my online/offline/AFK status

This setting places a question mark icon next to your name in people's contact lists where the online checkmark of AFK icon would otherwise be displayed to indicate that you are online or in "Away From Keyboard" (AFK) mode.

Hide my current world

This setting allows you to hide which world you are currently in so that it will not be displayed next to your name in people's contact lists.

By default, if someone else has you on their contact list, they will be able to see what world you are in when you are logged in.

Block join requests

With this option set, if anyone tries to send you a join request they will receive a message stating that their request to join was refused.

Block file transfers

With this option set, if anyone tries to send you a file they will receive a message stating that you did not accept their File Transfer request.

Note that for security reasons, you will always be asked to verify a file transfer request before it is accepted.

Other Settings

Confirm join requests

Causes a confirmation message to be displayed when someone tries to join you.

Automatically leave AFK mode on keyboard activity

Leaves AFK mode automatically when you start typing.
