-Please note that there are **no** privacy provisions on the OStatus network.
-Any message which is delivered to **any** OStatus member is visible to anybody in the world and will negate any privacy settings that you have in effect.
-These messages will also turn up in public searches.

-Since OStatus communications do not use authentication, if you select the profile privacy option to hide your profile and messages from unknown viewers, OStatus members will **not** be able to receive your communications.

-To connect with an OStatus member insert their profile URL or Identity address into the Connect box on your [Contacts](contacts) page.

-The GNU Social connector may be used if you wish posts to appear on an OStatus site using an existing OStatus account. 
-It is not necessary to do this, as you may 'follow' OStatus members from Friendica and they may follow you (by placing their own Identity Address into your 'Connect' page).
